Steps to Reproduce

1. Open the Claude CLI.
2. Paste a block of text containing Japanese characters.
3. Observe that the application immediately closes after displaying the error message.

Expected Behavior

The expected behavior is that the Claude CLI should correctly handle and display Japanese text without triggering errors or causing the application to close.

Actual Behavior

Upon pasting Japanese text, the application fails to find a wrapped line in the original text, resulting in an error that causes the CLI to close unexpectedly.

Additional Context

• This issue may be related to how the tool processes text wrapping, especially for non-Latin characters.
• It could also indicate a potential bug in the text measurement or wrapping functionality within the CLI.
• Please include any additional logs, screenshots, or details about your configuration (e.g., Node.js version, specific settings) when reporting this issue to facilitate troubleshooting.
