I had problems with subject encoding and 2-byte (japanese) characters.
especially with a mix of single-byte (ASCII) and 2-byte (japanese)
characters in the subject.  This problem was specifically noticable with
long subject lines that would need to be split in the headers.

it's been awhile since i've used RT (I changed jobs) so I don't remember
specifically the situation, but if I remember correctly, RT didn't
properly MIME encode the subject.  either it didn't properly terminate
and re-initiate the encoding per-line during a split, or if it did,
there were problems with it.

eventually I had to install Jcode.pl and use its encoding routines to
fix the problem for japanese.  This is probably related to the problems
you're seeing, although not likely Jcode.pl will have much effect on non
2-byte characters.

Either way, I suggest looking at the mail source to see the encoded
Subject: header information and check for problems there.
