Added item to the troubleshooting wiki page:

http://master.wiki2.dovecot.org/Pigeonhole/Sieve/Troubleshooting#Mailbox_Names_with_non-ASCII_Characters_Cause_Problems

By the looks of it, you are also using the RoundCube SieveRules plugin. 
The solution for RoundCube mentioned in the wiki should solve it for you.
