I cannot reproduce.  You are getting this error from the IMAP server:

C: 5 UID SEARCH CHARSET UTF-8 FROM maiko
S: 5 NO UTF-8 character set is not supported.

But with the latest version of IMP (5.0.22), this is impossible due to  
the code in IMP_Imap#_search().  At least once a session, we  
explicitly check whether UTF-8 is supported via a test query (the  
validSearchCharset() call on line 488 of IMP_Imap).   Sure enough, I  
see this on a server that doesn't support UTF-8:

C: 8 SEARCH CHARSET UTF-8 BODY a 1
S: 8 NO UTF-8 character set is not supported.

...and later, my actual search query:

C: 3 UID SEARCH FROM test
S: * SEARCH
S: 3 OK SEARCH done.

which doesn't use UTF-8 and instead directly uses US-ASCII.

Not sure what is wrong on your system.  Maybe your version of IMP is too old?
