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.

…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).

@w1semannn I just pushed a follow-up runtime fontconfig fix for macOS:
Could you please test the latest artifact again with the same scenario? |
Test results: commit 15e669d — fix not effectiveGX-ISSUE144 log is identical to the previous build. The fontconfig override is not taking effect: There is no fontconfig output in the log at all — no initialization messages, no mention of /System/Library/Fonts/Supplemental being scanned, no Arial Unicode MS being selected anywhere. System font inventory confirmedSo the correct font exists on the system. The issue is fontconfig not resolving to it. Possible causes
Suggested fixThe reliable approach is an explicit substitution rule with <match target="pattern">
<test qual="any" name="family">
<string>Arial</string>
</test>
<edit name="family" mode="prepend" binding="strong">
<string>Arial Unicode MS</string>
</edit>
</match>This forces fontconfig to prepend Arial Unicode MS whenever Arial is requested, so the first match will always be the Cyrillic-capable font. Additionally, it would help to add a startup log line showing the resolved physical path for the Arial family (e.g. via |
…deFont from reusing the same base family\nwhen unicode font config resolves to the same name (e.g., Arial),\nforcing fallback to continue into Unicode-capable candidates.\n\nThis targets Issue #144 macOS Cyrillic caption rendering path.
|
I pushed a new follow-up fix in commit 8de42b1 targeting the circular fallback path: When the base font and the preferred Unicode font resolve to the same family (for example Arial), we now skip that reuse and continue to the next Unicode-capable candidates instead of stopping at Arial. Could you please test the latest artifact again |
