I assume it's a mapnik issue, but it comes from openstreetmap.
http://www.openstreetmap.org/?lat=31.515602&lon=-9.767221&zoom=18&layers=M

the "زنقة الملاح" (road of the mellah) is rendered with so much space after the lam-alif glyph (لا) that it seems to be separated from the "ح" immediately following it.

thanks for the report. I've added to the list of text rendering issues at https://github.com/mapnik/mapnik/wiki/InternationalText

1 is the way it looks now, 2 is what I would expect.
which part of the code is involved, I'd like to have a look at it, was it just out of curiosity!
(I uploaded to dropbox, is there a way to upload to github?)

This bug should be fixed when we switch to HarfBuzz as our shaping engine. It shouldn't need any special handling.
