utf8 chars in email titles [#590910]

When sending email using the conditional actions, we get several unwanted chars in the email subject
=?UTF-8?Q?your order a beaut=C3=A9
should be
your order a beauté

This seems to be a encoding problem (utf8) of some kind. Help is very much appreciated.

It looks like the mail subjects should be run through mime_header_encode(), but the output you have there doesn't match what it should be giving.

mime_header_encode() adds =?UTF-8?B? to the beginning of the encoded string where yours has Q?. I suppose this can happen if you are using a different SMTP library file that implements drupal_mail_wrapper().

Moving this to a support request as it doesn't seem like a bug. The standard Drupal mail function will pass the Subject through mime_header_encode(), as noted in #1. This is essential because RFC 2822 governing mail states that only printable ASCII must be used for the subject. So when you use é anywhere in the subject, that triggers the base64 encoding of the subject. Again as noted in #1, what you are seeing is *not* the way the Drupal default mailer encodes the Subject line, so it seems you have plugged in a different mailer. Without more information from you, it seems clear that your different mailer is what is causing the problem.
