Fix double-width characters disappearing when wrapping

## Type of changes

- [x] Bug fix
- [ ] New feature
- [ ] Documentation / docstrings
- [ ] Tests
- [ ] Other

## Checklist

- [x] I've run the latest [black](https://github.com/psf/black) with default args on new code.
- [x] I've updated CHANGELOG.md and CONTRIBUTORS.md where appropriate.
- [x] I've added tests for new code.
- [x] I accept that @willmcgugan may be pedantic in the code review.

## Description

Update wrapping logic to fix issues with CJK charcters disappearing when the "fold" location sat *within* a double-width character. Ensure we retain browser logic of: 


> if there is no space on the current line, move to a new line, and if theres not enough space on the entire new line, fold the text over multiple lines at appropriate locations.

Adds some additional tests and docstrings, documentation etc.

Fixes #3176 

The wrapping process is overall still quite simple and doesn't match the browser in many cases. For example, wrapping does not consider punctuation (lines can begin with punctuation), and whitespace is handled differently (but practically speaking it seems sensible).
