broken subject when submitting issue via email written in japanese
TMail class in ActionMailer::Base decodes subject to ISO-2022-JP when the subject is written in Japanese. But it should be utf8 when set to issue.subject. As a result, we get broken subject like the attached picture.

- File mail_hander_broken_attachment_filename.diff added
- Status changed from Closed to Reopened
The same problem is on the filename of attachment files.
Attached patch fixes this in a similar way to mail_hander_broken_subject.diff.
However, I wonder where the String#toutf8 method came from.
Only kconv.rb (bundled in Ruby 1.8 series) defines String#toutf8,
and Redmine does not require this library, as far as I know.
Just in case, toutf8 from kconv uses nkf internally,
NKF.nkf decodes MIME encoded string automatically.

This change broke other non-JP and non-English encodings, plus I believe that TMail was handling your subject correctly (the problem may lie elsewhere).
Jean Philippe seems to have fixed it in sandbox some months ago...
