Subject: feat(editor): handle new multibyte sequences in normal mode
 replacement

while the implementation is not tied to screen chars, it is a reasonable
expectation to support the same size. If nvim is able to display a
multibyte character, it will accept the same character as input,
including in normal mode commands like r{char}
