# Port Upstream PRs #1038, #1045, #1037, #1019

## Task

Manually port 4 open upstream PRs into the `mod/sync-upstream-PRs` branch, pull in Romanian translations from `upstream/master`, and create a MERGED.md tracking document.

## Changes Made

### PR #1038 (partial -- incremental fixes)
- `lib/Epub/Epub/ParsedText.cpp`: Added `.erase()` calls in `layoutAndExtractLines` to remove consumed words after line extraction (fixes redundant early flush bug). Also fixed `wordContinues` flag handling in `hyphenateWordAtIndex` to preserve prefix's attach-to-previous flag.

### PR #1045 (direct string changes)
- Updated `STR_FORGET_BUTTON` in all 9 translation yaml files to shorter labels.
- Pulled `romanian.yaml` from `upstream/master` (merged upstream PR #987).

### PR #1037 (4-file manual port)
- `lib/Utf8/Utf8.h`: Added `utf8IsCombiningMark()` utility function.
- `lib/EpdFont/EpdFont.cpp`: Added combining mark positioning in `getTextBounds`.
- `lib/Epub/Epub/hyphenation/HyphenationCommon.cpp`: Added NFC-like precomposition for common Western European diacritics in `collectCodepoints()`.
- `lib/GfxRenderer/GfxRenderer.cpp`: Added combining mark rendering in `drawText`, `drawTextRotated90CW`, `drawTextRotated90CCW` (mod-only), and `getTextAdvanceX`. Also wrapped cursor advance in `renderCharImpl` to skip combining marks.

### PR #1019 (1-file manual port)
- `src/activities/home/MyLibraryActivity.cpp`: Added `getFileExtension()` helper and updated `drawList` call to show file extensions in the File Browser.

### Tracking
- `mod/prs/MERGED.md`: Created tracking document with details for all 4 PRs.

## Build Verification

`pio run -e mod` succeeded (24.49s, Flash: 57.2%, RAM: 31.4%).

## Follow-up Items

- All 4 upstream PRs are still open; monitor for any review feedback or changes before they merge.
- Romanian yaml is missing mod-specific string translations (using English fallbacks).
- PR #1019 open question: how file extensions look on long filenames.
