33660	EmailMessage encode the subject in base64 when translated and contains non US-ASCII characters	Yann	nobody	"The usual behavior of the EmailMessage class regarding its subject is to keep it as it is if i contains only US-ASCII characters and to encode it as quoted-printable if it contains non US-ASCII characters.

That works well and avoid our emails to be considered as pishing by antispam from email servers 

But in the specific context of translations there is a bug -> if the subject of an email is translated into another language (through the built-in django translations tools) and contains non US-ASCII characters, by an mechanism I didn't catch, the subject is encoded as base64 and not quoted-printable. 

This results in being considered as spam by the email servers (tested on Gandi and Gmail)..."	Bug	closed	Core (Mail)	4.0	Normal	needsinfo	EmailMessage Translation base64 quoted-printable		Unreviewed	0	0	0	0	0	0
