What's the penetration now for mail clients that send in UTF-8? Will the 
elephant in the corner (Exchange, OE) do that? Or does it insist on sending 
in "legacy" charsets like 1251? Not that I'm sure universal UTF-8 (with no 
errors) will help, but it's one less complication in the format, and lack 
of it might eventually become a strong spam sign.
