When exporting an issue list to CSV, if the issue list has a non-us ascii character, a 500 is produced with this in the logs:

ArgumentError (invalid byte sequence in US-ASCII):

Changing this in source:/trunk/app/controllers/issues_controller.rb@4515 fixed it, at least in that it does the export (non-ascii characters still don't seem quite right but they never really do and at least it exports).

As visible above, just added .force_encoding() there.
