8bit mime support? (linked to thunderbird issue)

[JL]

Hi,

I wanted to open a ticket on GPGME because thunderbird team says they 
can't encode email using 8bit mime because of GPGME not handling 
correctly 8 bit content

https://bugzilla.mozilla.org/show_bug.cgi?id=1966019

8bit RFC is 30 year old, using base64 to "keep compatibility with old 
not maintained server/client" is energy/storage/network inefficient.

the thunderbird teams introduce workaround instead of working with GPG 
team to have the issue fixed.... seems that non gpg email are 8bit mime 
on thunderbird for the main message, base64 for the attachements

would be nice to have the issue fixed so that base64 mime could be 
dropped, but don't know what is the issue they faced... maybe someone 
can participate on the thunderbird ticket so that the subject can go on?

thanks and regards
