The "@" symbol fails to trigger the "Files & Folders" menu when typed between Chinese characters in Cursor's prompt input box

Describe the Bug

When using Cursor’s prompt input area with Chinese text, the “@” symbol does not trigger the expected file selection menu when inserted between Chinese characters. This prevents users from easily referencing files using the “@” functionality when working with Chinese text. The issue can be worked around by inserting spaces around the “@” symbol, but this shouldn’t be necessary.

Steps to Reproduce

  1. Open Cursor and navigate to the prompt input area
  2. Type Chinese text: “请解释这个源文件的代码” (Please explain the code of this source file)
  3. Position the cursor after the word “解释” (explain)
  4. Type “@” to attempt adding a file reference (e.g., “@App.tsx”)
  5. Observe that no “Files & Folders” menu appears

Expected Behavior

When typing “@” in the prompt input area, regardless of the surrounding characters (including Chinese characters), the “Files & Folders” menu should appear, allowing users to select and reference files. The “@” functionality should work consistently across different languages and character sets.
