RFC-2822 says that raw SMTP headers should contain nothing but 7-bit
ASCII. If you wish to use international character sets or UTF-8 it should
be encoded (either QuotedPrintable or Base64, see ISO-2022).
Raw 8-bit characters can cause problems with older programs and are a
source of confusion. (Raw high-8 bit characters mean different things
depending upon the default character-set in use by the recipient.)
(IMAP server authors get upset over this issue as they have to deal
with parsing headers for searching & sorting.)
QP solves both of those issues, with little additional overhead.
Modern mail clients automatically take care of this.
Raw 8-bit headers are an indication of spam or a broken client and
rightly shunned.
As I assume that you're not a spammer, this means that your mail client
is not following international standards and needs to be updated.
