Hi Michael,

Well that's embarrassing, I could have sworn that was the first thing I
tried. I knew about the octets, and had tried inputting a\303\251b as
the search string, but was sure I'd also tried the plain old search
string. Thanks!

While I've got you here, I hope you'll answer one more question: what's
the format for searching multiple terms with non-ascii strings? Is it
possible in one run to find a utf-8 encoded subject, and a utf-8 encoded
body?

Thanks again,
Eric
