Hi,

Yes, I would like to support unicode. At first, reading this

Note that wide (East Asian full width) runes occupy two cells, and attempts to place character at next cell to the right will have undefined effects. Wide runes that are printed in the last column will be replaced with a single width space on output.

made me think there is no good way to deal with it. But the mattn/go-runewidth package appears to have all the functions that are needed.

I will get back to you when I have it.

I've added support for wide characters. Please have a look. If you still see issues with that, please let me know.

By the way, if you have a short code example with Chinese characters that you can send me, I'm happy to include it in the demos and the wiki.
