Unicode crash, byte_slice(): Byte range does not align with char boundaries

[Kelatte]

Summary

I'm using ibus to type Chinese characters, and when a line reaches a const limit and there is "<***>" in the document, an error occurs.

The error message is

thread 'main' panicked at /usr/share/cargo/registry/ropey-1.6.1/src/slice.rs:703:23:
byte_slice(): Byte range does not align with char boundaries: range 2..4

Reproduction Steps

I tried this:

1. hx a.tex
2. I typed the la<space>.

I expected this to happen:

The word "来" should be inserted.

Instead, this happened:

Helix unexpectedly crushed.

Debugging:

I tried to reduce some characters in the line and found that this only happens when a line reaches a limit. And it only happens when there is highlighted characters, such as <***>.

In the video below, I remove the <***> and it doesn't happen again.

Are you able to replicate this on a buffer with no set language? It could be an upstream issue with the latex tree-sitter grammar.
