dovecot - Dec 2013 - German Umlauts in folder name and sieve

Hi,

I had created an imap folder that has German Umlauts in it:

?RA R??ner - Merle?

When finished, the result looks like this on filesystem:

drwx------  3 vmail vmail 4096 Dec 27 11:02 RA Ro&AwgA3w-ner - Merle/

I wrote this sieve script (with SOGo):

if anyof (address :regex "from"
"@.*\\.ra-roessner-merle\\.de") {
    fileinto "RA Ro&AwgA3w-ner - Merle";
    stop;
}

That creates a new IMAP folder with exactly this strange name.

Can I change this somehow?

You need to put the imap folder name (fileinto "RA R??ner - Merle";) 
instead of directory name into your sieve script. More info in documentaton:
