as they occur in From/To headers, for example: "From:
=?iso-8859-2?Q?Krist=FDna?= <k@example.com>". we are using net/mail to parse
such headers. most address-parsing functions in that package will only decode
charsets utf-8, iso-8859-1 and us-ascii. we have to be careful to always use
net/mail.AddressParser with a WordDecoder that understands more that the
basics.
for issue #204 by morki, thanks for reporting!
