Creating a mail filter ends with Soap Error: target_error_regex
I use Roundcube and Mailuser interface plugin. When I try in Roundcube to create filter which move mails to folder with national chars in name (for example testovací with í ) I get this warning:
Soap Error: target_error_regex
The same result is when target folder is as subfolder of folder with national chars. When I use another folder without these chars filter is sucessfully created.
