Hi, 

Could you explain why you want this a bit more? 

It seems to me that to use multbyte fonts in GTK, you will
have to know the font's encoding, if you are loading the
font directly. In that case, you already know the fonts
width.

On the other hand, if you are using fontsets (for instance,
if you are using the XIM features of GDK), GDK uses 
multibyte (variable width) strings. It does not make
sense to ask for the number of bytes of a fontset,
since it can include both 8 and 16 bit fonts.

Future versions of GTK will have more complete support
for i18n, and will probably use wide characters internally.

Why both? What does font_width represent?
