Feedback - AI Response Language Preference (Traditional Chinese)

Support Help
1

Hello Cursor Support Team,

I am a Cursor paid user.

Issue Description:

When using Agent / Chat, even though I ask questions in Traditional Chinese, the AI often replies in Simplified Chinese, which does not match my usage preference.

For example, responses may use Simplified terms such as “根据”, “规格”, “发射”, and “标注” instead of the Traditional equivalents “根據”, “規格”, “發射”, and “標註”.

I have already set a User Rule: “Always respond in 中文”, but the Agent still tends to output Simplified Chinese and does not consistently follow my Traditional Chinese preference.

Request:

  1. Could Cursor provide an option for “Default to Traditional Chinese (Taiwan)”, or automatically match the user’s input language?
  2. Could you explain how the AI response language is currently determined? Is it related to model region, system language, or User Rules?
  3. Can User Rules be made more reliable for enforcing Traditional Chinese output in Agent responses?

Environment:

  • Cursor version: 3.10.11
  • OS: Windows 10 (Build 22631)
  • Language / Region: Traditional Chinese (Taiwan)

Please let me know if you need additional information or screenshots. Thank you for your help.

Hey @RkoJax

Thanks for the detailed writeup! There isn’t a dedicated language setting right now. Language mostly comes from the context of your conversation and code plus your User Rules, not from model region or your system language.

Usually, models picks up your language from context and matches it. The problem is that the context can get “poisoned”: if your code, comments, or existing files contain Simplified Chinese, the model tends to drift toward Simplified no matter what you type. And 中文 on its own doesn’t pin it down, since it covers both variants.

I’d suggest a stronger rule that names the exact variant and gives a few examples so the model can self-check. Try replacing Always respond in 中文 with this in your User Rules:

# Language: Traditional Chinese (Taiwan) only
- Always reply in Traditional Chinese (繁體中文 / zh-TW).
- NEVER use Simplified Chinese characters (简体字), even if my message,
  the code, or comments contain them.
- Use Taiwan vocabulary. For example:
  根据 → 根據, 规格 → 規格, 发射 → 發射, 标注 → 標註,
  软件 → 軟體, 程序 → 程式, 数据 → 資料, 默认 → 預設.
- Keep code, APIs, file paths, and commands unchanged — only prose
  should be Traditional Chinese.
