832593 - Encoding-detection of attached text files for all relevant mime types

Status: UNCONFIRMED

Description

[Martin Girschick]

User Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en; rv:1.9.2.28) Gecko/20120308 Camino/2.1.2 (like Firefox/3.6.28)
Build ID: 20120308211433

Steps to reproduce:

I attached an XML file (encoded in UTF-8) to a mail.


Actual results:

The encoding was not detected correctly and now charset was added to the content-type MIME attachment header.


Expected results:

The encoding should be detected properly. Not only for text/plain file as per https://bugzilla.mozilla.org/show_bug.cgi?id=636112 but for all text subtypes.
