Wordwrap and "full-width" characters of Chinese/Japanese/Korean

[ksze]

Is the wordwrap filter smart about full-width characters?

Usually a full-width character from the CJK languages is considered to have the width of two ASCII characters.

This is important for wordwrapping plain text.

The wordwrap filter uses Python's textwrap library and this does not fit well with Chinese/Japanese/Korean characters. I've seen this bug in so many programs.

The problem is simple but the solution I'm afraid that will not reach soon. It seems that Python is missing a reliable Unicode Line Breaking Algorithm implementation, so the high level developers opt for the ASCII-oriented textwrap, which doesn't have a good unicode support (there are some variants of the same bug in bugs.python.org#41975, izimobil/polib#96, AFPy/powrap#76 and mondeja/mdpo#153 (comment)).
