vim-patch:8.2.2606: strchars() defaults to counting composing characters
Problem: strchars() defaults to counting composing characters.
Solution: Add strcharlen() which ignores composing characters.
https://github.com/vim/vim/commit/70ce8a1561c5396e4c4381f76a005cbb97646f80
Use docs from latest Vim instead.
