Redmine

It should be noted that I am receiving emails using pop and the patch in Issue #2420 but I don't think the problem lies with this.

When I try and send emails to the redmine server with Japanese characters in them it appears to work apart from the pattern matching.

For example if I send an email with the following keywords.

Project: happi
Tracker: 開発

The email is processed but it isn't assigned to the correct tracker and "Tracker: " appears in the issue body.
However it does get assigned to the correct project. I am assuming that the pattern matching cannot handle the UTF-8 encoded Japanese (or all multi-byte?) characters.
