There are two main encodings for czech language, "windows-1250" and "iso-8859-2". Output (PDA) encoding is usually first one, but huge number of web pages is written in second one.
Latest version of Sunrise XP couldn't handle this -- for example site
http://www.root.cz/ ends with error in update log: type="text/html (iso-8859-2)", status="error: Error transcoding characters".
Sunrise 0.42 works like a charm.
