afraid to start digging. :) I'll take a look at that - thanks.
We actually thought of the table of widths approach, but it's incredibly
cumbersome, especially considering we need to deal with multiple point
sizes, and also variations (bold/italic). I'm hoping to avoid that. :)
Thanks!

(not char count)
If you're not scared of Java, one approach would be to use the
java.awt.FontMetrics class (probably via a temp image's Graphics
instance), specifically the getStringBounds method. That'll
give you
all kinds of goodies about the font and strings written using
that
font.
If you don't want that complexity, you could record the pixel
width of
each character in your desired font into a struct, and loop over
the
string, summing up a length. Won't be exactly perfect, because
of
ligatures and kerning, but it should be close, and I believe
that'll
never underestimate, but that'll might not be true.
cheers,
