Mapnik currently uses the ICU library which I believe implements some of this already: http://www.icu-project.org/ The main issue with multilingual rendering on the Mapnik layer is that the code only supports using a single font for all the text on the map. Currently we use the DejaVu fonts which have a reasonable coverage but not enough for everyone to be happy. http://dejavu.sourceforge.net/ Jon _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
