Problems with czech characters

[Eckard_Buchner]

Hello,
our Czech customers tell us that not all czech characters are printed correctly with the built-in pdf fonts. For example "R-caron" is not part of the font table in the pdf specification.
If we embed a true type font then it is fine, but we have not found a suitable font to ship with our application (license restrictions or heavy license fees)

Has anybody experienced similar problems? How can I make use of the fonts that acrobat reader comes with (Minion ...). Are these fonts available on all platforms?
These fonts contain most foreign characters

Thanks
Eckard
