How to send e-mails using utf-8? does anyone know if you can send emails using utf-8 instead of ascii in CraftCMS 2?

I am using the Freeform plugin to send entries from a "Contact Us" form to a CRM that needs to receive the e-mails in utf-8 but they are coming in as ASCII. Is there a way to change this in either the plugin or in Craft? 

Thank you!
Craft 2 uses PHPMailer for its email sending library.

It does have a public CharSet property that Craft explicitly sets to UTF-8 when sending emails.

The problem is, they have logic that overwrites our UTF-8 value in certain circumstances... namely when no 8-bit characters are involved in the body setting it to us-ascii: https://github.com/PHPMailer/PHPMailer/blob/master/src/PHPMailer.php#L2453-L2458

Not sure of a good resolution as this seems like undesired behavior in the PHPMailer library to me.

FWIW, the upcoming Craft 3 has ditched PHPMailer in favor of Swift Mailer where it is much more customizable.
