IME callback crashes application

[abhishekp106]

Description

The application I'm developing that depends on winit crashes here. My application panics with Invalid UTF-8 String from IME: Utf8Error { valid_up_to: 0, error_len: Some(1) }. It seems to be due to the IME String failing to be proper UTF-8. Is there a way winit could fail in a safer way than crashing here?

I don't have a repro as this happened on another user's machine.

OS and window mananger

Operating System: Ubuntu
Window Manager: XWayland

Winit version

This will be fixed in the upcoming refactoring of IME in X11.

Maybe just discard the invalid values? Not sure how doing lossy conversion will work here, maybe just fine...
