From: Karl Hasselström <kha@xxxxxxxxxxx>
Having non-ascii characters in email headers is illegal, but StGIT
currently does not care. I'm often bitten by this, since my name
doesn't fit in ascii.
This patch implements an encoding pass just before the email is sent
over the wire -- in particular, it comes after any interactive editing
and templates and such, so the user should never have to see the
rfc2047 encoding.
NOTE: The rfc2047 encoder needs to know the encoding of the input
string. This patch hard-codes this to utf8, since that should be by
far the most common non-ascii encoding, and since utf8 is already the
hardcoded character set for the email body. In the long run, we
probably want to get this from the locale, or from a command line
switch, or both.
