Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [ ] Unsafe blocks (if any) have justifying comments
- [x] The content is consistent with the [UI/UX
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
- [ ] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Resolves the issues described at
https://github.com/pop-os/cosmic-text/releases/tag/0.19.0
This fix addresses the characters '\u{001C}' | '\u{001D}' | '\u{001E}' |
'\u{0085}' | '\u{2029}', which can cause the Editor gpui-component to
crash, as these characters can cause the 'assert "left == right"'.

Release Notes:
- N/A
