Both, depending on whether client-side core X fonts are used or
whether client-side fonts are used with Xft.

I don't understand this question -- a font is a collection of
descriptions of outlines, including curves and/or code to draw
the glyphs as well as other metadata.  Are you asking if the
instructions to draw an "a" (for example) are sent in ascii over
the connection to the X server, or are you really trying
to ask if pango can render non-latin text?  If the latter, yes
it can, see www.pango.org.  if the former, no, the connection to
the X server must be 8-bit clean as it's binary data.

pango controls this.  And yes if pango calls XDrawString() then
XDrawString() will be used. Gdk may also draw text directly,
without pango, I think.

I hope this helps, but I suspect all I can do is help you to
phrase your question more precisely, or to describe what you
are trying to do so people can give a better answer.
