complicated font styles will probably not work so well... you should stick to simpler fonts, as a general rule.
I created my own font maps, which seemed to work ok. you just create a png with transparent background with the letters as big as you need them & add "_" before each line...
_ 1 2 3 4 5 6 7 8 9 0
_ a b c d e f g h i j k l m
_ n o p q r s t u v w x y z
_ A B ...
as long as the spacing is ok & the letters don't have gaps in between them like : ä etc then they should work ok providing you add a bit of stroke fx to them.
