[Zope] ZSyncer and accented chars in title

When source document has accented characters in its title, it *is* synced successfully but it cannot it synced from then on. ZSyncer gives error message: "Syntax error at line 31: illegal character in content" How can I fix it? I'm using accented character from ISO-8859-2 set (Czech characters). I'm using ZSyncer 0.3 and Zope 2.4.3 under Linux. -- Milos Prudek
