Mime mail module and RTL support?

Hi there,
I've been trying to figure if there's a way to enable the mime module (http://drupal.org/project/mimemail) to support RTL (hebrew, arabic) emails.
I managed to work out with htmlmail (http://drupal.org/project/htmlmail) module to support RTL Emails, but MANY modules depend on the mime mail module.
Does anyone had experiense with that?
