Does not support multibyte characters (e.g Chinese)

it will mess up the splited window border.

That is almost true, the underlying library I use doesn't support CJK characters unfortunately. At the moment there is nothing I will do about it, but maybe in future I'll add support for that somehow. The reason why it's so hard, because termbox works by assumption that each character takes exactly one cell, with CJK runes it's not true, they take two.

But other multibyte characters which take one cell should work just fine.

Actually should work now, can you please test it?

I can confirm that it works like a charm now. CJK characters are well supported.
