ActionMailer encoding


I am using ActionMailer to recieve emails as per the usual method. I use postfix.

My Database is setup for utf8 encoding. I get a database error when I try to store email.body into a record in the database. This means that action mailer is returning the body string in the original email encoding.

abstract_adapter.rb:128:in `log': RuntimeError: ERROR C22021 Minvalid byte sequence for encoding "UTF8": 0x92

Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1

How should I handle this? Must I use Iconv to manually convert this data by examining the content-type field of the email? The body must end up in utf8 form when it gets stored into the database.
