[Bug/Feature] Fix IME input for Vietnamese, Chinese, Japanese, Korean (character loss)

A standalone tool that wraps Claude Code and fixes IME input:

npm install -g terminal-ime-proxy
timp claude  # Run Claude Code with IME fix

How it works:

1. Intercepts keyboard input
2. Detects IME characters
3. Buffers composition
4. Sends complete characters to Claude Code

Proposed Fix for Claude Code

If you'd like to fix this directly in Claude Code, here's the approach:

1. Option A: Wait for React Ink PR to be merged and update dependency

1. Option B: Create a custom IMETextInput component that buffers input:

// Pseudocode for IMETextInput
const IMETextInput = ({ value, onChange }) => {
  const [buffer, setBuffer] = useState('');
  const timeoutRef = useRef(null);

  useInput((input, key) => {
    if (isIMEInput(input)) {
      // Buffer IME input
      setBuffer(prev => prev + input);
      clearTimeout(timeoutRef.current);
      timeoutRef.current = setTimeout(() => {
        onChange(value + buffer);
        setBuffer('');
      }, 50);
    } else {
      // Flush buffer and handle regular input
      if (buffer) {
        onChange(value + buffer);
        setBuffer('');
      }
      // Handle regular input
    }
  });
};

Affected Languages

| Language | Input Methods | Users Affected |
|----------|---------------|----------------|
| Vietnamese | Telex, VNI, VIQR | ~97 million |
| Chinese | Pinyin, Wubi | ~1 billion+ |
| Japanese | Romaji | ~125 million |
| Korean | Hangul | ~80 million |
| Thai | Standard | ~70 million |

Environment

• OS: Windows 11
• Terminal: Windows Terminal
• IME: Unikey (Vietnamese Telex)
• Claude Code: Latest version

Workaround (Current)

Until this is fixed, users can use the terminal-ime-proxy tool:

npm install -g terminal-ime-proxy
timp claude

Request

Please consider:

1. Monitoring the React Ink PR and updating when merged
2. Or implementing an internal fix using the approach above
