What happened?

When opening the gemini-cli within the VS Code integrated terminal and attempting to type in Korean (Hangul), It appears that the keystrokes might be captured in the underlying buffer, but the output dosent work to input box.

What did you expect to happen?

Korean characters should be typed, composed, and rendered normally in the CLI input prompt within the VS Code terminal.

Anything else we need to know?

  1. Tool Comparison: Other competitor CLI tools work flawlessly within the same VS Code integrated terminal without any input issues.

  2. Reinstallation: Completely reinstalling the gemini-cli does not resolve the behavior.

  3. Environment Constraint: The current environment utilizes the Snap version of VS Code, and changing this specific setup is highly difficult.

  4. Standalone Terminal Works: Executing node gemini-cli in a standard standalone terminal emulator + bash environment works perfectly. However, this disrupts the workflow as it makes simultaneously viewing code very inconvenient.

  5. Preference for CLI: GUI extensions (like Gemini Chat) are not preferred due to various feature constraints. A fix for the normal Korean input in the VS Code terminal, as it used to function, is highly anticipated.

  6. Regression Timeframe: Unfortunately, it is currently unclear exactly when this issue first started occurring. Apologies for the lack of a specific version timeframe.

extent analysis

TL;DR

  • Investigate the encoding or input handling differences between the VS Code integrated terminal and a standalone terminal emulator to resolve the Korean input issue in the gemini-cli.

Guidance

  • Compare the terminal settings and environment variables between the VS Code integrated terminal and the standalone terminal emulator where the gemini-cli works as expected.
  • Verify if the issue persists when using a different input method or language in the gemini-cli within the VS Code terminal.
  • Check for any known issues or limitations in the Snap version of VS Code that might be contributing to the problem.
  • Test the gemini-cli in a different IDE or text editor's integrated terminal to isolate if the issue is specific to VS Code or its Snap version.

Notes

  • The fact that the issue does not occur in a standalone terminal emulator suggests that the problem might be related to the interaction between the gemini-cli and the VS Code integrated terminal.
  • The use of the Snap version of VS Code might impose specific constraints or limitations that could be contributing to the issue.

Recommendation

  • Apply workaround: Use the gemini-cli in a standalone terminal emulator until a fix for the VS Code integrated terminal issue is found, as it allows for uninterrupted workflow and simultaneous code viewing, albeit with some inconvenience.
