[cm3]

I cannot use st because it still has corner cases that xterm works well but st doesn't yet, and I find the need to patch the sources hard to maintain when a new release comes out and has refactorings included.

But I must say that st's font rendering of Unicode is more complete than rxvt-unicode or xterm. With the same font configured in all three, st is the one that manages to render the most glyphs of plan9port's unicode sample file. Would be great to have the same in urxvt or xterm.
