czech diacritics for Macs

[clark troy]

Dear colleagues,

A friend of mine who's a graphic designer needs to get her hands on a
font and/or keyboard driver which will let her do Czech diacritic marks on
a Macintosh.  Does anyone know where one can get such a thing, esp.
downloadable versions on the web or at FTP sites?

Please respond off list to me or directly to my friend at
dalyannb at interport.net.  Her name is Ann.

Many thanks in advance,

Clark Troy
