fix(fonts): add unicode fallback for cyrillic#145
Conversation
Improve AlternateUnicodeFont resolution on macOS/Linux by trying configured Unicode font first and then a deterministic fallback list of common system fonts. Also update the May 2026 dev diary before commit as required by project workflow. Fixes #144

Quick Status Update
✅ What's Working Now
After the CSF fallback fix and Unicode font fallback:
- Tooltip text - Cyrillic now renders correctly
- Window/Unicode font paths - Working as expected
- CSF label fallback - Incomplete override packages no longer cause missing labels
⚠️ What's Still Missing
The reporter identified two specific failures that appear to be font-slot specific:
- Construction captions -
Строительство: XX%above buildings (completely absent) - Build-cost line - Missing from tooltips (rest of tooltip renders fine)
Hypothesis
These failures point to the DrawableCaptionFont path, which may:
- Not be using the same Unicode fallback chain as tooltip paths
- Have a different font resolution mechanism
- Be affected by a font-slot-specific issue on macOS
Next Investigation Focus
- Trace
DrawableCaptionFontconstruction and loading - Check if
LoadUnicodeFallbackFontis called for this slot - Add targeted debug logging for font selection in caption paths
- Compare caption vs tooltip rendering code paths
Action Items
- Monitor GitHub Actions build status
- Request reporter to test latest artifact
- Prepare debug logging for
DrawableCaptionFontpath - Document exact code divergence between caption and tooltip paths
Status: Awaiting reporter validation of latest build

Technical Deep Dive - Font Slot Analysis
Understanding the Problem Hierarchy
Based on the reporter's feedback, we can map the rendering paths:
┌─────────────────────────────────────────────────────────────┐
│ RENDERING PATHS │
├─────────────────┬─────────────────┬─────────────────────────┤
│ Tooltip Text │ Construction │ Build-Cost Line │
│ (WORKING ✅) │ Caption │ (MISSING ❌) │
├─────────────────┼─────────────────┼─────────────────────────┤
│ Font Slot: │ Font Slot: │ Font Slot: │
│ DefaultWindow │ DrawableCaption│ Unknown/Tooltip │
│ (Unicode) │ (Caption) │ (Unknown) │
├─────────────────┼─────────────────┼─────────────────────────┤
│ Path: │ Path: │ Path: │
│ Unicode font │ Caption font │ Tooltip font │
│ stack │ stack │ stack │
└─────────────────┴─────────────────┴─────────────────────────┘
Key Observations
- Tooltip text works → Unicode fallback is functional for at least one path
- Construction captions fail →
DrawableCaptionFonthas different behavior - Build-cost line fails → Same or similar font slot as captions
Investigation Plan
Phase 1: Code Path Analysis
Files to examine:
Core/GameEngine/Source/GameClient/- Text renderingCore/GameEngine/Source/GameClient/GameFont/- Font managementCore/GameEngine/Source/GameClient/GUI/- GUI rendering
Search terms:
DrawableCaptionFontcaption+fontconstruction+textbuild+cost+tooltip
Phase 2: Font Slot Registration
Check where font slots are registered and loaded:
- Look for
DrawableCaptionFontregistration - Compare with
DefaultWindowFontregistration - Identify if they use different loading mechanisms
Phase 3: Debug Logging Strategy
Proposed logging points:
// In font loading path
LOG_DEBUG("Font slot: DrawableCaptionFont");
LOG_DEBUG("Requested font: %s", fontName);
LOG_DEBUG("Resolved font: %s", resolvedFont);
LOG_DEBUG("Unicode fallback enabled: %d", isUnicodeFallback);
LOG_DEBUG("Glyph lookup result: %d", glyphIndex);Expected Findings
I expect to find that:
DrawableCaptionFontuses a different loading path thanDefaultWindowFont- The Unicode fallback may not be triggered for caption fonts
- There may be a font cache or slot-specific issue
Next Actions
- Search codebase for
DrawableCaptionFontusage - Compare caption vs tooltip font loading code
- Prepare debug logging patches
- Document exact code divergence points
Status: Analysis phase - ready to implement debug logging

Action Plan - Next Session
Immediate Actions (This Session)
- ✅ Document current state - Done
- ✅ Add status comments to PR - Done
- ⏳ Search codebase for DrawableCaptionFont - Pending
- ⏳ Identify font loading paths - Pending
Investigation Steps
Step 1: Find DrawableCaptionFont Usage
# Search for all references to DrawableCaptionFont
grep -r "DrawableCaptionFont" --include="*.cpp" --include="*.h" .
# Search for caption-related font code
grep -r "caption" --include="*.cpp" --include="*.h" . | grep -i "font"Step 2: Compare Font Loading Paths
- Find where
DefaultWindowFontis loaded (working path) - Find where
DrawableCaptionFontis loaded (failing path) - Identify the divergence point
Step 3: Prepare Debug Logging
Create a minimal debug logging patch that:
- Logs font slot name
- Logs requested vs resolved font
- Logs Unicode fallback status
- Logs glyph lookup results
Expected Timeline
- Session 1: Code search and path identification
- Session 2: Implement debug logging
- Session 3: Analyze debug output and identify root cause
- Session 4: Implement fix and validate
Success Criteria
- Identify exact code path divergence between caption and tooltip rendering
- Confirm whether Unicode fallback is skipped for caption fonts
- Prepare targeted fix that doesn't break working paths
Status: Planning complete, ready to begin code search

Technical Analysis - Unicode Fallback Implementation
Current State
The PR #145 proposes adding LoadUnicodeFallbackFont() to apply Unicode fallback for Cyrillic rendering.
What We Discovered
Working Path (DefaultWindowFont)
- Uses
winFindFont()with Unicode fallback - Font loaded via
GameWindowManager::winSetFont() - Unicode fallback applied at font loading time
Failing Path (DrawableCaptionFont)
- Uses
winFindFont()without Unicode fallback - Font loaded via
InGameUI::init() - No Unicode fallback applied
Key Finding
The Unicode fallback is font-slot specific, not global:
- Only applied to
DefaultWindowFont(window/tooltip path) - Not applied to
DrawableCaptionFont(caption/world path)
Proposed Solution
Add LoadUnicodeFallbackFont() call to apply Unicode fallback to caption fonts.
Questions for Investigation
-
Why is Unicode fallback only applied to DefaultWindowFont?
- Is it intentional (caption fonts assumed Latin-only)?
- Is it a bug (should apply to all Unicode fonts)?
-
Will applying Unicode fallback to DrawableCaptionFont work?
- Font slot-specific caching may interfere
- Different rendering path may bypass fallback
-
What is the best place to apply Unicode fallback?
- At font loading time (current PR approach)
- At font rendering time
- Globally for all font slots
Next Steps
- Review PR #145 implementation details
- Test if Unicode fallback works for caption fonts
- If successful, consider making it global
- If not successful, investigate font slot-specific caching
Status: Awaiting PR review and testing

Hi @fbraz3 — can't test the new build, the macOS Zero Hour artifact The compile errors are in L1401: Get_Sync_Frame_time → did you mean Get_Sync_Frame_Time (Twelve errors total in macOS-vulkan / generalsxzh@macos-vulkan job.)

Tested build 9df81a3, GX-ISSUE144 diagnostics confirm the root cause. Key log lines: [GX-ISSUE144] GlobalLanguage init Language.ini fallback chain not implemented The problem is a circular fallback: drawableCaption=Arial, unicode fallback=Arial. Root cause: Language.ini fallback chain is not implemented (as logged), so the russifier's The tooltips (Times New Roman) work through a different path — likely the system fontconfig Attaching filtered log (GX-ISSUE144 lines only). |
…descriptors (Issue #144) When russifier mod (00RussianZH.big) loads an incomplete Language.ini with UnicodeFontName=\"Arial\", it permanently overrides the stock \"Arial Unicode MS\" which supports Cyrillic. Since Arial lacks Cyrillic, construction captions render blank on macOS. Now when registryLanguage != \"English\", load stock English/Language with INI_LOAD_MULTIFILE mode to fill missing keys. This restores UnicodeFontName to \"Arial Unicode MS\" while preserving legitimate russifier overrides. Mirrors existing CSF fallback pattern (commit 3a28555). Fixes #144 Affects GeneralsXZH only (Language.ini path pattern) - GlobalLanguage::init() now loads stock Language.ini as fallback - Updated stderr diagnostics to show primary + fallback resolution - Expected fix: construction captions \"Строительство: XX%\" now render

Summary
Fixes missing Cyrillic UI labels on macOS by improving Unicode fallback font resolution in the W3D font loading path.
Changes
