feat(fonts): implement universal font resolution with bundled liberation fonts - #336
Conversation
…ion fonts - Bundle SIL OFL Liberation Fonts v2.1.5 (arial, arialbold, couriernew, timesnewroman) under assets/fonts/ with license attribution. - Add scripts/env/setup-fonts.sh for reproducible checksum verification and font staging. - Implement multi-tiered font resolution in FontCharsClass::Locate_Font_FontConfig: 1. Tier 1: Probe local and bundled fonts/ directory (app bundle, game root, CWD). 2. Tier 2: Query system Fontconfig (desktop Linux/macOS). 3. Tier 3: Guaranteed fallback to bundled arial.ttf / arialbold.ttf. - Guard fontconfig.h with TargetConditionals to skip Fontconfig on iOS. - Add Liberation Sans to fallback and full coverage font lists in W3DGameFont. - Update macOS app bundling and Linux Flatpak manifests to stage fonts. - Update docs/WORKLOG/2026-09-DIARY.md with implementation details.

In `@Core/GameEngineDevice/Source/W3DDevice/GameClient/GUI/W3DGameFont.cpp`:
- Around line 163-169: Remove “Liberation Sans” from the kFullCoverageFonts list
so it is not treated as a full-coverage font and the existing fallback can
select an alternate Unicode font.
In `@Core/Libraries/Source/WWVegas/WW3D2/render2dsentence.cpp`:
- Around line 1700-1707: Update the font alias checks in the candidate-selection
logic to recognize only exact normalized aliases for Arial, Times/Times New
Roman, and Courier/Courier New, including their bold variants, so Unicode font
names do not select narrow substitutes. Apply the same recognized-alias
predicate to the Tier 3 fallback loop, preventing unrelated unresolved names
from selecting arial.ttf before later fallback candidates.
- Around line 1731-1765: Update the font search directory setup to resolve and
add the macOS app bundle’s Contents/Resources/fonts path, so lookup finds the
staged fonts when launched from the external game-data directory. Keep the
/app/share/fonts candidate unchanged for Flatpak; use the existing search_dirs
lookup boundary or pass the resolved bundle path from the macOS launcher.
In `@scripts/build/macos/bundle-macos-generals.sh`:
- Line 350: Update the font-staging steps in the macOS bundle scripts and
Flatpak manifests to copy assets/fonts/LICENSE.liberation alongside the staged
Liberation TTF files, ensuring every output that includes those fonts also
includes their license.

Description
Implements a universal, multi-tiered font resolution subsystem and bundles metric-compatible Liberation Fonts v2.1.5 (SIL Open Font License 1.1) to guarantee consistent, crash-free text rendering across Linux, macOS, and future portable platforms (such as iOS) without relying strictly on host
Fontconfigor proprietary Microsoft fonts.Motivation & Background
Fontconfig(Locate_Font_FontConfig) to resolve fonts like "Arial" and "Generals". On bare macOS installations, minimal Linux/Flatpak environments, or iOS (where Fontconfig does not exist), font resolution would fail completely or select misaligned fallback fonts, causing UI layout glitches, missing text, or crashes in Save/Load/Replay menus.Arial.ttf,Times New Roman, etc.) are proprietary and cannot be legally redistributed. Liberation Fonts (Liberation Sans, Liberation Serif, Liberation Mono) are SIL OFL 1.1 licensed and metrically compatible with Microsoft Core Fonts, with broad Unicode coverage (Latin, Extended Latin, Cyrillic, Greek).ammaarreshi/Generals-Mac-iOS-iPad).Changes
