The UI is strange when using Japanese input.

What happened?

When I inputted Japanese characters, characters were displayed outside the message box.

What did you expect to happen?

When you enter Japanese characters, they should be displayed in the message box in the same way as when you enter the alphabet.

Summary

This issue was originally reported as a bug related to detecting in-progress (unconfirmed) IME input in an Ink-based CLI app.
After investigation, it turns out that this is not a bug, but a fundamental limitation of Node.js and terminal environments.

Findings

Ink relies on Node.js’s process.stdin, which only receives finalized (committed) input strings.
It does not support detecting composition events during IME input (such as when selecting kanji before pressing Enter).

Issue Resolution

As this behavior is a known limitation of terminal-based environments and not a bug,
we are closing this issue with the above explanation.
Thank you for your understanding!
