[Dovecot] Problem with sieve and german umlauts

[M. Bobkiewicz]

Dear list,
I?m running a postfix (2.5.6) / Dovecot (1.1.11) on a Centos 5.2 box. 
I?ve written a small gui application to simply create Out of Office 
replys with sieve. The resulting code did work with maildrop without any 
problems. Now sieve fails when it meets any german umlauts like ä or ü. 
It just stops compiling the scripts and complains about the missing 
"};". A simple fix is to just replace the umlauts, but that doesn?t meet 
the expectations of my users. Is there any escape code I could use or 
any way to place the mail text outside the script?

Best regards,

 Mike
