I am using r1064 and command line I use is:

java -Xmx1024m -ea -jar mkgmap.jar -n 62233665 --family-id=773
--series-name="OSM Macedonia-INT"  \
--family-name="OSM_MKD_INT" --overview-mapname=40000773 --net --route
--country-name=MACEDONIA \
--country-abbr=MKD --road-name-pois --add-pois-to-areas --no-poi-address
--tdbfile --gmapsupp \
--description="OSM_MKD_INT" --name-tag-list="int_name,name:en,name"
OSM_MKD.osm

Which produces gmasupp.img (and same with 62233665.img) with lowercase
letters inside  In my mobile device, only capital letters are shown, i.e.
first letters of names of cities, streets on the map or only capital letters
of POIs under POI search. Mapsource shows first letter as capital and shows
rest as lower-case.

The OSM data is in unicode (i.e. bbox=21.32,41.92,21.55,42.08 where you can
find lots of it). I also use slightly modified row04.trans (attached) to add
transliteration to some extended cyrilic letters (i.e. U+0403 = Gj) plus
slight change to transliteration standard (i.e. U+0425 = 'H' istead of
'Kh'), which unfortunately depends on each country...

I guess it is possible to modify row tables to transiterate everything to
captial ASCII, however i was hoping it is more systematic that everithing is
captilized after transliteration pass if --lower-case option is not given.

Thanks,
Ivan
