Just a tip for those wanting to send emails with double-byte character sets (eg. big5), there are two things that can screw you up:
1. CI's native Email class does a stripslashes() on the message content when preparing the mail. I would suggest extending the Email class and removing the stripslashes() call from the message() function.
2. Wordwrap - make sure you turn it off in your email configuration (it defaults to true) because it may split a double-byte character.
