Unity Localization — Multi-Language Support

Localization package for Unity 6 (com.unity.localization). Full pipeline for strings, assets, and locale management.

Setup

1. Install com.unity.localization via Package Manager
2. Edit → Project Settings → Localization → Create Localization Settings
3. Add locales: Locale Generator → select languages → Create
4. Create string tables: Assets → Create → Localization → String Table Collection

String Tables

Table: "UI"
├── Key: "menu_start"    → EN: "Start Game"    | VI: "Bắt đầu"     | JP: "ゲーム開始"
├── Key: "menu_options"  → EN: "Options"        | VI: "Cài đặt"     | JP: "オプション"
└── Key: "menu_quit"     → EN: "Quit"           | VI: "Thoát"       | JP: "終了"

Table: "Gameplay"
├── Key: "health_label"  → EN: "Health: {0}"   | VI: "Máu: {0}"
└── Key: "score_format"  → EN: "Score: {0:N0}" | VI: "Điểm: {0:N0}"

Key Gotchas

1. Async loading: Strings load asynchronously. Use StringChanged event, not direct access
2. Missing entries: Falls back to key name. Set fallback locale in settings
3. Smart String escaping: Use \{ for literal braces
4. Locale codes: Use ISO 639-1 (en, vi, ja, ko, zh-Hans, zh-Hant)
5. Font coverage: CJK languages need large font atlases — use SDF fonts + fallback chains
6. RTL: TMPro supports RTL via isRightToLeftText. Test with Arabic/Hebrew early
