   This issue might be a duplicate of existing issues. Please check:

   • CJK characters break some features like @ mentions #3734: CJK characters break some features like @ mentions - This issue describes problems with CJK (Chinese, Japanese, Korean) character handling in opentui, including cursor positioning issues
   • Korean (Hangul) characters display as broken/garbled in input field #3493: Korean (Hangul) characters display as broken/garbled in input field - This issue reports similar display problems with Korean characters appearing broken/garbled in the input field

   Both issues involve CJK character display problems in opentui, similar to the strange characters appearing between Chinese characters reported here.

   Feel free to ignore if none of these address your specific case.
