With the CVS version of imapfilter (it supports the "charset" IMAP4rev1
parameter while searching) and using UTF8 as the charset, I was able to
succesfully filter a message with english, greek polytonic, russian and
german characters (I used a Unicode editor to compose the message and
create imapfilter's config file).  The mail server must also support
other charsets than ASCII in order to do this.  I don't know if trying
the CVS version with UTF8 as charset, will be of any help, though.

I can't really tell why the filter fails (i18n support and workarounds
such as RFC1522 tend to cause headaches), but can you try something
simpler in the filter? Trial and error might prove useful with your
problem...

Use this:

...
action move "&BB8EPgQ0BD8EOARBBDoEMA-/EMS 1C"
