AFAIK, depending on the font, the width of a string is not the same as
the sum of the width of all its characters. OTOH, I think you can assume
that the width of a string will always be <= than the sum of the width of
its characters. So adding the box of each glyph should give you a maximum
width anyway.

Note that I'm not a font expert, so I might be wrong.
