I agree that using something like Pango or HarfBuzz is the only sensible
way to go though as trying to reimplement shaping for all the languages
would be a massive job.
Yeah, that's the point. Mapnik already has an enormous amount of work
to do nice placement and rendering of elements, it would be good if it
could re-use the text rendering logic from an existing library.
Again, especially for the Arabic language, doing the text rendering is
immensely difficult, reinventing the wheel here is not a good idea.
Well Arabic is the one language mapnik already manages to handle, but
the method it uses to do so isn't supported for other languages, and
can't work for all languages because Unicode doesn't have the necessary
distinct codepoints in some cases.
I'm not clear how much better HarfBuzz is from a dependency point of
view - it is still built on top of GLib so looks much the same to me
from that point of view.
I don't know either, I've never heard of HarfBuzz before.
I hadn't heard of it until a week or two ago, either. Details for
anybody that is interested are here:
