email from trac have a bad encoding

[blogv2@…]

When emails are sent from tickets they are sent with the following header : Content-Type: text/plain; charset="us-ascii"

We have a project in french and tickets have many non-ascii characters like "é". Those characters are correctly sent in UTF-8 but with charset="us-ascii" many mail client use ISO-8859-1 per default.

To be correctly rendered by mail clients, e-mails should be sent with the following header instead : Content-Type: text/plain; charset="utf-8"
