the real issue at hand is that mapnik does not render words as one
entity. hence the problems with languages in which characters are
different depending on their position in the word.

using something like pango may be required for proper text output. thing
is, I'm not sure antigrain can do that. the only rendering library that
can do that properly as far as I know is cairo
