[horde] imap search: missing CHARSET UTF-8 string

Hello Michael,

I did not find any BADCHARSET notice in the imap log (logged over a  
period for more than 2 days). hm...

Ok, thanks, we'll try to have a deeper look into this part.

Interesting notice! We got the feedback that the sort order in imp has  
influence about the search results. Something magic is going on  
here... (:
