## Summary
**What is the goal of this PR?**
This change fixes an issue I noticed while reading where occasionally,
especially in italics, some words would have too much space between
them. The problem was that word width calculations were including any
negative X overhang, and combined with a space before the word, that can
lead to an inconsistently large space.

## Summary
* During chapter parsing, every <img> tag triggered ZIP decompression
and an SD card write regardless of whether the image format was
supported. The mandatory delay(50) after each SD write compounded the
cost. A chapter with 6 GIF images (a common decorative element in older
EPUBs) wasted ~750 ms before any text rendering began.
* **What changes are included?**
Added an ``ImageDecoderFactory::isFormatSupported()`` check before any
file I/O in the img-handler. Only JPEG and PNG proceed to extraction;
all other formats (GIF, SVG, WebP, etc.) fall through immediately to
alt-text rendering with no SD card access.
## Additional Context
Measured impact on a representative chapter with 6 GIF decorations:
| | Before | After|
|-- | -- | --|
|Total parse time | ~882 ms | ~207 ms|
|Image handling | ~750 ms | ~76 ms|

## Summary
**What is the goal of this PR?**
Compress reader font bitmaps to reduce flash usage by 30.7%.
**What changes are included?**
- New `EpdFontGroup` struct and extended `EpdFontData` with
`groups`/`groupCount` fields
- `--compress` flag in `fontconvert.py`: groups glyphs (ASCII base group
+ groups of 8) and compresses each with raw DEFLATE
- `FontDecompressor` class with 4-slot LRU cache for on-demand
decompression during rendering
- `GfxRenderer` transparently routes bitmap access through
`getGlyphBitmap()` (compressed or direct flash)
- Uses `uzlib` for decompression with minimal heap overhead.
- 48 reader fonts (Bookerly, NotoSans 12-18pt, OpenDyslexic) regenerated
with compression; 5 UI fonts unchanged
- Round-trip verification script (`verify_compression.py`) runs as part
of font generation

## Summary
I want to preface this PR by stating that the proposed changes are
subjective to people's opinions. The following is just my suggestion,
but I'm of course open to changes.
The popups in the currently implemented version of the Lyra theme feel a
bit out of place. This PR suggests an updated version which looks a bit
more polished and in line with the rest of the theme.
I've also taken the liberty to remove the ellipsis behind the text of
the popups, as they made the popup feel a bit off balance (example
below).
With the applied changes, popups will look like this.
The vertical position is (more or less) aligned to be in line with the
sleep button. I'm aware the popup is used for other purposes aside from
the sleep message, but this still felt like a good place. It's also a
place where your eyes naturally 'rest'.
The popup has a small 2px white outline, neatly separating it from
whatever is behind it.
### Alternatives considered and rationale behind proposal
Initially I started out worked off the Figma design for the Lyra theme,
which [moves the
popups](https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1)
to the bottom of the screen. To me, this results in popups that are much
too easy to miss:
After this, I tried moving the popup back up (to the position of the
sleep button), but to me it still kinda disappeared into the text of the
book:
Inverting the colors of the popup made things stand out the perfect
amount in my opinion. The white outline separates the popup from what is
behind it.
This looked much better to me. The only thing that felt a bit off to me,
was the balance due to the ellipsis at the end of the popup text. Also,
"Entering Sleep..." felt a bit.. engineer-y. I felt something a bit more
'conversational' makes at all feel a bit more human-centric. But I'm no
copywriter, and English is not even my native language. So feel free to
chip in!
After tweaking that, I ended up with the final result:
_(Same picture as the first one shown in this PR)_

## Summary
**What is the goal of this PR?**
In some places, button labels are omitted intentionally because the
button has no purpose in the activity. I noticed a few obvious cases,
like Home > File Transfer and Settings > System > Language, where the up
and down button labels were missing. This change fixes those and all
similar instances I could find.

## Summary
Continue my experiment from
https://github.com/crosspoint-reader/crosspoint-reader/pull/801
This PR add the ability to lower the CPU frequency on extended idle
period (currently set to 3 seconds). By default, the esp32c3 CPU is set
to 160MHz, and now on idle, we can reduce it to just 10MHz.
Note that while this functionality is already provided by [esp power
management](https://docs.espressif.com/projects/esp-idf/en/v4.3/esp32c3/api-reference/system/power_management.html),
the current Arduino build lacks of this, and enabling it is just too
complicated (not worth the effort compared to this PR)
Update: more info in
https://github.com/crosspoint-reader/crosspoint-reader/pull/852#issuecomment-3904562827
## Testing
Pre-condition for each test case: the battery is charged to 100%, and is
left plugged in after fully charged for an extra 1 hour.
The table below shows how much battery is **used** for a given duration:
| case / duration | 6 hrs | 12 hrs |
| --- | --- | --- |
| `delay(10)` | 26% | 48% |
| `delay(50)`, PR
https://github.com/crosspoint-reader/crosspoint-reader/pull/801 | 20% |
Not tested |
| `delay(50)` + low CPU freq (This PR) | Not tested | 25% |
| `delay(10)` + low CPU freq (1) | Not tested | Not tested |
(1) I decided not to test this case because it may not make sense. The
problem is that CPU frequency vs power consumption do not follow a
linear relationship, see
[this](https://www.arrow.com/en/research-and-events/articles/esp32-power-consumption-can-be-reduced-with-sleep-modes)
as an example. So, tight loop (10ms) + lower CPU freq significantly
impact battery life, because the active CPU time is now much higher
compared to the wall time.
**So in conclusion, this PR improves ~150% to ~200% battery use time per
charge.**
The projected battery life is now: ~36-48 hrs of reading time (normal
reading, no wifi)

**What is the goal of this PR?**
Several methods in GfxRenderer were doing a `count()` followed by `at()`
on the fonts map, effectively doing the same map lookup unnecessarily.
This can be avoided by doing a single `find()` and reusing the iterator.

## Summary
* **What is the goal of this PR?** Fix a dangling pointer issue caused
by using `.c_str()` on a temporary `std::string`.
`basepath.substr()` creates a temporary `std::string`, and calling
`.c_str()` on it returns a pointer to its internal buffer (not a copy).
Since the temporary string is destroyed at the end of the full
expression, `folderName` ends up holding a dangling pointer, leading to
undefined behavior.
To solve this, we stores the result in a persistent `std::string`
object, ensuring the underlying buffer remains valid for the duration of
its use.
A similar pattern caused the behavior reported in
https://github.com/crosspoint-reader/crosspoint-reader/pull/728#issuecomment-3902529697

Currently, the battery icon and charge percentage were aligned to the
left even for the UI, where they were positioned on the right side of
the screen. This meant that when changing values of different numbers of
digits, the battery would shift, creating a block of icons and text that
was illegible.

headers
- Keep drawBattery() for left-aligned display in reader mode
- Extract drawBatteryIcon() helper to reduce code duplication
- Battery icon now stays fixed at right edge regardless of percentage
digits
- Text adjusts to left of icon in UI mode, to right of icon in reader
mode

Empty Button Icons (I.E. Back button in the home menu) were still
rendering the full sized white rectangles going passed the boarders of
the little button nub. This was not visible on the home screen due to
the white background, but it does cause issues if we ever want to have
bmp files displayed while buttons are visible or implement a dark mode.
* **What changes are included?**
Made it so that when a button hint text is empty string or null the

passed the bounds of the mini button nub
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,

Having that extended rectangle was likely never noticed due to the only
space where that feature is used being the main menu where the
background is completely white. I am working on some new features that
would have an image displayed while there are button hints and noticed
this issue while implementing that.
One other note is that this only affects the Lyra Theme

**What is the goal of this PR?**
This PR introduces Internationalization (i18n) support, enabling users
to switch the UI language dynamically.
**What changes are included?**
- Core Logic: Added I18n class (`lib/I18n/I18n.h/cpp`) to manage
language state and string retrieval.
- Data Structures:
- `lib/I18n/I18nStrings.h/cpp`: Static string arrays for each supported
language.
- `lib/I18n/I18nKeys.h`: Enum definitions for type-safe string access.
- `lib/I18n/translations.csv`: single source of truth.
- Documentation: Added `docs/i18n.md` detailing the workflow for
developers and translators.
- New Settings activity:
`src/activities/settings/LanguageSelectActivity.h/cpp`
This implementation (building on concepts from #505) prioritizes
performance and memory efficiency.
The core approach is to store all localized strings for each language in
dedicated arrays and access them via enums. This provides O(1) access
with zero runtime overhead, and avoids the heap allocations, hashing,
and collision handling required by `std::map` or `std::unordered_map`.
The main trade-off is that enums and string arrays must remain perfectly
synchronized—any mismatch would result in incorrect strings being
displayed in the UI.
To eliminate this risk, I added a Python script that automatically
generates `I18nStrings.h/.cpp` and `I18nKeys.h` from a CSV file, which
will serve as the single source of truth for all translations. The full
design and workflow are documented in `docs/i18n.md`.
- [x] Python script `generate_i18n.py` to auto-generate C++ files from
CSV
- [x] Populate translations.csv with initial translations.
Currently available translations: English, Español, Français, Deutsch,
Čeština, Português (Brasil), Русский, Svenska.
Thanks, community!
**Status:** EDIT: ready to be merged.
As a proof of concept, the SPANISH strings currently mirror the English
ones, but are fully uppercased.

Currently, each activity has to manage their own `displayTaskLoop` which
adds redundant boilerplate code. The loop is a wait loop which is also
not the best practice, as the `updateRequested` boolean is not protected
by a mutex.
In this PR:
- Move `displayTaskLoop` to the super `Activity` class
- Replace `updateRequested` with freeRTOS's [direct to task
notification](https://www.freertos.org/Documentation/02-Kernel/02-Kernel-features/03-Direct-to-task-notifications/01-Task-notifications)
- For `ActivityWithSubactivity`, whenever a sub-activity is present, the
parent's `render()` automatically goes inactive
With this change, activities now only need to expose `render()`
function, and anywhere in the code base can call `requestUpdate()` to
request a new rendering pass.
In theory, this change may also make the battery life a bit better,
since one wait loop is removed. Although the equipment in my home lab
wasn't been able to verify it (the electric current is too noisy and
small). Would appreciate if anyone has any insights on this subject.
Update: I managed to hack [a small piece of
code](https://github.com/ngxson/crosspoint-reader/tree/xsn/measure_cpu_usage)
that allow tracking CPU idle time.
The CPU load does decrease a bit (1.47% down to 1.39%), which make
sense, because the display task is now sleeping most of the time unless
notified. This should translate to a slightly increase in battery life
in the long run.

## Summary
* I am getting miniz warning during compilation: "Using fopen, ftello,
fseeko, stat() etc. path for file I/O - this path may not support large
files."
* Disable the io module from miniz as it is not used and get rid of the
warning
## Additional Context
* the ZipFile.cpp implementation only uses tinfl_decompressor,
tinfl_init(), and tinfl_decompress() (low-level API) and does all ZIP
file parsing manually using SD card file I/O
* it never uses miniz's high-level file functions like
mz_zip_reader_init_file()
* so we can disable Miniz io-stack be setting MINIZ_NO_STDIO to 1

## Summary
* If an EPUB has:
```
<dc:creator>J.R.R. Tolkien</dc:creator>
<dc:creator>Christopher Tolkien</dc:creator>
```
the current result for epub.author would provide : "J.R.R.
TolkienChristopher Tolkien" (no separator!)
* The fix will seperate multiple authors: "J.R.R. Tolkien, Christopher
Tolkien"
## Additional Context
* Simple fix in ContentOpfParser - I am not seeing any dependence on the
wrong concatenated result.

* The constant SETTINGS_CONST was hardcoded and needed to be updated
whenever an additional setting was added
* This is no longer necessary as the settings size will be determined
automatically on settings persistence
* New settings need to be added (as previously) in saveToFile - that's
it

This PR applies a micro optimization on `SerializedHyphenationPatterns`,
which allow reading `rootOffset` directly without having to parse then
cache it.
It should not affect storage space since no new bytes are added.
This also gets rid of the linear cache search whenever
`liangBreakIndexes` is called. In theory, the performance should be
improved a bit, although it may be too small to be noticeable in
practice.

## Summary
* **What is the goal of this PR?**
Currently, the battery icon and charge percentage were aligned to the
left even for the UI, where they were positioned on the right side of
the screen. This meant that when changing values of different numbers of
digits, the battery would shift, creating a block of icons and text that
was illegible.
* **What changes are included?**
- Add drawBatteryUi() method for right-aligned battery display in UI
headers
- Keep drawBattery() for left-aligned display in reader mode
- Extract drawBatteryIcon() helper to reduce code duplication
- Battery icon now stays fixed at right edge regardless of percentage
digits
- Text adjusts to left of icon in UI mode, to right of icon in reader
mode
## Additional Context
* Add any other information that might be helpful for the reviewer
* This fix applies to both themes (Base and Lyra).

Not much else to say here. I did simplify the logic in lyratheme.cpp
based on there no longer being a requirement for any non-cover specific
rendering differences.

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Empty Button Icons (I.E. Back button in the home menu) were still
rendering the full sized white rectangles going passed the boarders of
the little button nub. This was not visible on the home screen due to
the white background, but it does cause issues if we ever want to have
bmp files displayed while buttons are visible or implement a dark mode.
* **What changes are included?**
Made it so that when a button hint text is empty string or null the
displayed mini button nub does not have a white rectangle extending
passed the bounds of the mini button nub
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
Having that extended rectangle was likely never noticed due to the only
space where that feature is used being the main menu where the
background is completely white. I am working on some new features that
would have an image displayed while there are button hints and noticed
this issue while implementing that.
One other note is that this only affects the Lyra Theme

## Summary
**What is the goal of this PR?**
This PR introduces Internationalization (i18n) support, enabling users
to switch the UI language dynamically.
**What changes are included?**
- Core Logic: Added I18n class (`lib/I18n/I18n.h/cpp`) to manage
language state and string retrieval.
- Data Structures:
- `lib/I18n/I18nStrings.h/cpp`: Static string arrays for each supported
language.
- `lib/I18n/I18nKeys.h`: Enum definitions for type-safe string access.
- `lib/I18n/translations.csv`: single source of truth.
- Documentation: Added `docs/i18n.md` detailing the workflow for
developers and translators.
- New Settings activity:
`src/activities/settings/LanguageSelectActivity.h/cpp`
## Additional Context
This implementation (building on concepts from #505) prioritizes
performance and memory efficiency.
The core approach is to store all localized strings for each language in
dedicated arrays and access them via enums. This provides O(1) access
with zero runtime overhead, and avoids the heap allocations, hashing,
and collision handling required by `std::map` or `std::unordered_map`.
The main trade-off is that enums and string arrays must remain perfectly
synchronized—any mismatch would result in incorrect strings being
displayed in the UI.
To eliminate this risk, I added a Python script that automatically
generates `I18nStrings.h/.cpp` and `I18nKeys.h` from a CSV file, which
will serve as the single source of truth for all translations. The full
design and workflow are documented in `docs/i18n.md`.
### Next Steps
- [x] Python script `generate_i18n.py` to auto-generate C++ files from
CSV
- [x] Populate translations.csv with initial translations.
Currently available translations: English, Español, Français, Deutsch,
Čeština, Português (Brasil), Русский, Svenska.
Thanks, community!
**Status:** EDIT: ready to be merged.
As a proof of concept, the SPANISH strings currently mirror the English
ones, but are fully uppercased.

I used AI for the black work of replacing strings with I18n references
across the project, and for generating the documentation. EDIT: also
some help with merging changes from master.
