I don't really know. But I think X server really don't know about
if a font is an Unicode font or not. It just looks up glyphs in the
font. Sure you cannot use single byte drawing functions to draw a char
greater than 255. Have you tried with XDrawString16 seriel of functions?
Just contruct the right XChar2b and draw glyph with it. "xfd" gives
the right index of glyphs in a font.
Of course use XDrawString16 directly broke Xlib's i18n. Then you
have to handle i18n yourself. unless those > 255 chars are just
some symbols, signs.
If it cannot, maybe the Type1 font driver in X does not know about
font with more than 255 chars.
The encoding information is used when doing i18nized drawing. like
fontset.
Maybe I mis-understood what you said.
Oh, my xlsfonts -ll -fn 'font name' does not give me any
min_byte1 max_byte1 entries.
