TL;DR

The issue with newlines after every character in the Claude Code Cli v2.1.109 UI on Windows may be related to incorrect encoding or terminal settings.

Guidance

  • Verify that the terminal settings in windows-terminal are correctly configured to handle the encoding used by Claude Code Cli.
  • Check if there are any known issues with the version 2.1.109 of Claude Code Cli that could be causing this problem.
  • Try running Claude Code Cli in a different terminal emulator to see if the issue is specific to windows-terminal.
  • Review the documentation for Claude Code Cli to ensure that it is properly configured for use on the win32 platform.

Notes

The lack of error messages in the Errors section makes it difficult to pinpoint the exact cause of the issue, and without more information about the configuration and setup of Claude Code Cli, it's challenging to provide a more specific solution.

Recommendation

Apply workaround: Try running Claude Code Cli in a different terminal emulator to isolate if the issue is terminal-specific, as this could provide more insight into whether the problem lies with the terminal settings or Claude Code Cli itself.
