Emoji character causes cursor unexpected behaviour

[heldrida]

Summary

While writing bash, put a small text message preceded by an emoji info character. It caused Helix Editor to show the cursor in odd places, and also some characters such as double quote to show/hide as I moved around hjkl or cursor keys.

Thus, when putting some emoji characters in-memory it causes Helix unexpected behaviour.

Reproduction Steps

I tried this:

1. Open a typescript file hx fooba.ts
2. Insert emoji ℹ️
3. Yank text/emoji selection
4. Paste text/emoji line
5. Move cursor around

I expected this to happen:

Work as regular character/text.

Instead, this happened:
