How can I generate an email with a subject line with international characters in it?

Question

The content encoding headers define how the body of the message is to be interpreted, but the subject is a header, and isn't subject (ha ha) to the declaration of the content type/encoding headers.

Is there a way to make international character set subject lines?

Answer 1

Yes. RFC 2047 specifies how.

Answer 2

http://tools.ietf.org/html/rfc2047 defines encoding of non-ascii characters in headers.

"=?" charset "?" encoding "?" encoded-text "?="
