Japanese IME (New Microsoft IME) input not working in Claude Code TUI on Windows 11

Description

Japanese input via the new Microsoft IME does not work in Claude Code's interactive TUI on Windows 11.

Steps to Reproduce

  1. Enable the new Microsoft IME (Windows 11 default)
  2. Launch claude command in Windows Terminal or PowerShell
  3. Try to type Japanese characters at the prompt

Expected Behavior

Japanese IME input works normally.

Actual Behavior

Japanese characters cannot be entered. IME appears to be blocked by Claude Code's TUI input handling.

Workaround

Switching to the legacy Microsoft IME (Settings > Time & Language > Language & Region > Japanese > Microsoft IME Options > General > 'Use previous version of Microsoft IME') restores Japanese input.

Environment

  • OS: Windows 11 Pro
  • Claude Code version: 2.1.193
  • Terminal: Windows Terminal (PowerShell 7.5.5)
  • IME: New Microsoft IME (incompatible) / Legacy Microsoft IME (works)
