Subject: vim-patch:8.2.4418: crash when using special multi-byte character

Problem:    Crash when using special multi-byte character.
Solution:   Don't use isalpha() for an arbitrary character.
https://github.com/vim/vim/commit/5921aeb5741fc6e84c870d68c7c35b93ad0c9f87

Rename vim_isalpha to mb_isalpha.
