Well, usually, if you have a fixed-width font, you don't have to worry
about the size of the glyphs - all have the same size. This
considerably simplifies the font handling.
Therefore, you could decide to ignore the double-width characters - in
any case, you need to handle them differently than other characters,
and you need extra code to do so.

One would think so :-)
But since those fonts are flagged to be monospace fonts, but then have
two different width, they are obviously either not monospace fonts, or
it is in fact something different - I don't know, though, I never had
any typographical lectures :-))
