OK, finally got it to work. I don't know what makes Gill Sans good enough to be picked up from the /fonts directory, but Amasis, Caecilia & Malabar were apparently still on the device even after I removed them from the upgrade file, being preferred to sideloaded versions. So, I added
Code:
rm -rf /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Amasis*.ttf
rm -rf /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Caecilia*.ttf
rm -rf /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Malabar*.ttf
to the end of
/etc/init.d/rcS and voila! Both advanced settings and Cyrillic letters are working. Happy camper
