# 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
