This is perfectly legal.  RFC 2047 supercedes RFC 822 and defines 
character encoding within headers, including the Subject: header.

Regarding the use of Ref: vs. Re:, there's nothing in RFC 822 that 
requires it to be one way or another.  Subject: is defined as a 
*text type, which expands to "any CHAR, including bare CR & bare LF, but
NOT including CRLF".

I agree that this is a better solution.
