TL;DR

The issue might be related to incorrect handling of Unicode characters when backspacing, and a potential fix could involve adjusting the input processing logic to correctly handle Unicode characters.

Guidance

  • Review the input processing logic to ensure it correctly handles Unicode characters, particularly when backspacing.
  • Verify that the issue is reproducible with different Unicode characters and input sequences to understand the scope of the problem.
  • Check if there are any existing issues or discussions related to Unicode character handling in the Gemini CLI project.
  • Consider testing the Gemini CLI with different operating systems and environments to see if the issue is platform-specific.

Notes

The provided information does not include specific details about the code or implementation, so a more detailed analysis or fix cannot be provided.

Recommendation

Apply workaround: Adjust the input processing logic to correctly handle Unicode characters, as this seems to be the most likely cause of the issue.
