ActionMailer content set to charset big5

Hi Guys,

I just fixed the problem in setting up the action_mailer
default_charset.

Now, I succeeded in sending email with content-type big5. HOwever, the
content of the email is still utf-8!

I’ve tried to call the .encode(‘big5’) for my content, but there is

“invalid byte sequence in UTF-8”

errors in a lot of places; and it stop me from hacking the gems.

Any help is appreciated!
