Example Interactions

Set Language

User: /language set en

Response:
Language preference updated to English.
Your preferred language: en

Get Language

User: /language get

Response:
Current language settings:
- Preferred language: English (en)
- Auto-detection: enabled
- Fallback language: English (en)

Disable Auto-Detection

User: /language auto off

Response:
Auto language detection disabled.
The system will always use your preferred language: en

Language Detection Logic

When auto_detect is enabled:

1. Analyze user input for Chinese character ratio
2. If Chinese characters > 30%, detect as zh-CN
3. Otherwise, detect as en
4. Store detection result in detected field
5. Use detected language for current response
