-# Fix for Garbled Japanese/Non-ASCII Text in Dropdowns
-
-## Problem
-Japanese, Korean, Chinese, and other non-ASCII characters were displaying as garbled/corrupted text in dropdown menus for:
-- Armature selection in Quick Access panel
-- Mesh selection in Visemes panel
-
-This is a known issue with Blender's EnumProperty system when using dynamic callbacks that return Unicode strings.
-
-## Root Cause
-Blender's EnumProperty RNA system can have encoding issues when:
-1. The enum items function is called multiple times with changing data
-2. Unicode strings in display names aren't properly cached
-3. The internal C API receives the same Python string object in different states
-
-## Solution
-Implemented proper caching with invalidation for EnumProperty items:
-
-### Changes Made
-
-1. **core/common.py** - Enhanced `get_armature_list()` function
-   - Added cache key based on (name, pointer) tuples
-   - Cache is invalidated only when actual objects change
-   - Prevents Blender from re-encoding strings on every access
-   - Added `clear_enum_caches()` helper function
-
-2. **core/properties.py** - Enhanced `get_mesh_objects()` function  
-   - Added same caching mechanism as armature list
-   - Cache key based on mesh objects (name, pointer)
-   - Stable cache prevents encoding corruption
-
-3. **core/common.py** - `get_mesh_from_identifier()` helper
-   - Converts safe identifier back to mesh object
-   - Handles both new format (`MESH_{pointer}`) and legacy format
-   - Returns None if mesh not found
-
-4. **ui/visemes_panel.py** - Updated mesh retrieval
-   - Uses `get_mesh_from_identifier()` instead of direct lookup
-
-5. **functions/visemes.py** - Updated all mesh access points
-   - All operators now use the helper function consistently
-
-## Technical Details
-
-### ASCII-Safe Identifiers
-- Dropdown identifier: `ARM_{memory_pointer}` or `MESH_{memory_pointer}` (ASCII-safe, unique)
-- Dropdown display: Original object name (preserves Unicode characters)
-- Backwards compatibility: Falls back to direct name lookup
-
-### Caching Strategy
-The cache uses function attributes to store:
-- `_cache_key`: Tuple of (name, pointer) for all relevant objects
-- `_cached_items`: The actual list of enum items
-
-Cache is invalidated when:
-- Objects are added/removed
-- Objects are renamed
-- Object pointers change (object recreated)
-
-This ensures Blender's RNA system receives the exact same Python string objects on subsequent calls, preventing encoding corruption.
-
-## Testing
-
-To verify the fix works:
-1. Create armature/mesh objects with Japanese/Korean/Chinese names (e.g., "アバター", "아바타", "化身")
-2. Open Quick Access panel - armature dropdown should display correctly
-3. Open Visemes panel - mesh dropdown should display correctly
-4. Select items - operations should work with the selected objects
-5. Rename objects - dropdowns should update and still display correctly

-## Note on prop_search
-The `prop_search` widget used for shape key/bone selection inherently handles non-ASCII characters correctly since it searches Blender's internal data structures directly, not custom enum properties.
