Yep, there's a problem here, thanks. I haven't got Lucida Typewriter,
but found my Vista install has Lucida Sans Typewriter. That font
doesn't actually have Greek or box drawing characters, so all I'm
getting is the square replacement character, but it does indeed take
up two cells for those. Turns out that's because Latin characters are
reported as having a width of 0.5 (of whatever unit) whereas the
replacement character is reported as being 0.625 wide. I'll adjust the
ambiguous-width detection.
