Describe the Bug

Thank you for Cursor. Japanese text gets garbled in Composer 2 Fast, but renders correctly in regular Composer and GPT on the same machine.

Steps to Reproduce

  1. Open Cursor on Windows 10.
  2. Use Composer 2 Fast.
  3. Ask for a somewhat long Japanese response.
  4. Some parts of the Japanese text become garbled.
  5. Switch to regular Composer (non-Fast).
  6. Ask for the same or similar Japanese response.
  7. Japanese renders correctly.
  8. GPT / normal chat also renders Japanese correctly.

Expected Behavior

Japanese text should render correctly in Composer 2 Fast, just like it does in regular Composer and GPT.
