Japanese strings sent before confirming

[moksahero]

I'm Japanese native speaker and use Japanese for prompt.

And Japanese (and many other Asian languages) works in a way that return key is used to confirm while choosing different characters. Pressing return key again sends the confirmed string. You can see this behaviour in terminal.

But chat screen in Claudia sends unconfirmed string at the first return key press instance and that is making me impossible to put together Japanese strings before sending it as a prompt.
