it's an osm xml from geofabrik downloads, so i'd expect it to be proper 
utf8 :)

so it might be that the file has properly encoded characters, but the 
device does not properly display them ?
if i "manually" compare what they look like on the gps device and 
onscreen, result on gps device seems to match what i get if i look at 
cp1257 (or iso-8859-13) encoded text in a unicode terminal...
