Unicode characters off with some fonts

[tsujigiri]

With some fonts it looks like the stones are cut off on the right side:

Not sure if this is fixable at all, since it depends not only on the fonts you are using but also on the terminal it runs in. It might be possible to hook into pango, which is used in the Gnome Terminal and others for fallback font selection, to directly influence the font selection. But this is just a wild guess.
