We are testing Mapnik (v0.7.0 & 0.7.1 on WinXP) for rendering map and we have found a strange bug in Mapnik's TextSymbolizer when dealing with Armenian letters (maybe also other letters?).

Here we provide some screenshots of the artifacts, some permalinks to OpenStreetMaps, and all the necessary files '''for reproducing the bug (see attachments)'''.

(We use "Tahoma Armenian Regular" font, but the bug exist when using other fonts too and depends from the "spacing" value)

You will need to create (if missing) a PostGIS enabled PostgreSQL database named "postgis", and import the SQL file to the database. Then run the slightly modified version of generate_tiles.py for generating the tiles. Then use "viewer/index.htm" to view the tiles using OpenLayers.
