[OSM-dev] OSM Mapnik Fonts are Nonsense

[maw269 at gmail.com]

I am having issues rendering non-English Alphabet fonts from Mapnik for an  
OSM world map tile server I am creating. I've done the research to no  
avail. I must be missing something. I am using Mapnik 0.7.1 on windows  
server 2008.

1. I have created a myOSM.xml stylesheet from the osm.xml template using:

generate_xml.py osm.xml myOSM.xml --dbname osm_planet --accept-none  
--password pw --host localhost --port 5432 --user postgres

2. After creating the xml I then downloaded the Winzip unifont archive for  
Mac and Windows from http://unifoundry.com/unifont.html  
(http://unifoundry.com/unifont-5.1.20080907.zip ).

3. I uzipped this to:

C:\mapnik-0.7.1\lib\mapnik\fonts

4. I then went to C:\mapnik-0.7.1\inc\fontset-settings.xml.inc and  
uncommented the unifont lines as such:

<!--Settings for Mapnik Fonts
Uncomment the unifont entries if you have that font installed
in your mapnik fonts dir, and want to use it as a fallback font.
Mapnik includes this font by default since r1328.
To see the fonts you have installed with Mapnik do:
ls `python -c "import mapnik;print mapnik.fontscollectionpath"`-->

<FontSet name="book-fonts">
<Font face_name="DejaVu Sans Book" />
<Font face_name="unifont Medium" />
</FontSet>
<FontSet name="bold-fonts">
<Font face_name="DejaVu Sans Bold" />
<Font face_name="unifont Medium" />
</FontSet>
<FontSet name="oblique-fonts">
<Font face_name="DejaVu Sans Oblique" />
<Font face_name="unifont Medium" />
</FontSet>

5. I then opened the myOSM.xml and noticed that it only had listed the  
DejaVu fonts at the top. I then added the unifonts as such:

<?xml version="1.0" encoding="utf-8"?>
<Map srs="+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0  
+y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs +over"  
bgcolor="rgb(181,208,208)">
<FontSet name="book-fonts">
<Font face_name="DejaVu Sans Book" />
<Font face_name="unifont Medium" />
</FontSet>
<FontSet name="bold-fonts">
<Font face_name="DejaVu Sans Bold" />
<Font face_name="unifont Medium" />
</FontSet>
<FontSet name="oblique-fonts">
<Font face_name="DejaVu Sans Oblique" />
<Font face_name="unifont Medium" />
</FontSet>

6. I then ran the following from the command prompt as suggested in  
http://sajjad.in/mapping/setting-up-mapnik-for-rendering-tiles-in-your-language/:

python
>>> from mapnik import *
>>> for face in FontEngine.face_names(): print face
… [Enter]

It listed the 'unifont Medium' so I figured I was good to go.

7. I started to create tiles for the world using generate_tiles.py

All the letters in Eastern Europe, Asia, the Middle East, North Africa and  
similar areas that don't use the english alphabet, are nonsense.

Can someone please help me?
