[TextInput] maxLength doesn't work correctly with multibyte characters

[ide]

As shown in #1945, TextInput's maxLength prop doesn't work with Chinese characters. It's probably looking at the number of bytes and should be counting codepoints or glyphs instead.

While we're at it, does anyone want to stress test the single/multiline TextInput components with all sorts of Unicode using Naughty Keyboard? https://github.com/Palleas/NaughtyKeyboard/

Probably a just need to use unicode length instead of byte length - want to send a PR?

I opened this since @monyxie mentioned it in #1945. Perhaps someone with non-English apps who needs this feature would like to work on it?

unicode length instead of byte length

It might be a little trickier than this if we want to limit the number of glyphs. IIRC combining diacritical marks take up multiple Unicode codepoints but are rendered as one character like ў.
