In a command line utility it is often nice to line things up in
columns. This is pretty easy if all you care about is English, but
becomes quite nasty when you have to deal with arbitrary display
character sets.
The problem is that a string has 3 lengths:
This presents us with a bit of a problem. We were planning on basing
all our character set hanlding on the iconv() interface, but that
doesn't handle the column-width of strings at all. Right now we
haven't solved this, but we will probably add a loadable interface for
a character set specific column count function.

I naively assumed in my initial plan that the character length and
number of columns would always be the same. Unfortunately that is not
the case, for example many Japanese characters consume 2 columns when
displayed.
