Steps to reproduce:

Simply responded to emails and double spaces in the email are replaced with ?? (i.e. two question marks).  Single spaces are not impacted.

Had similar problem before in which odd special characters were inserted any time a double space was used.  I changed the Text Encoding to Unicode (UTF-8) and that solved the problem.  Text Encoding is still Unicode (UTF-8).
This is a current problem with all e-mail services provided by AT&T, Yahoo, BellSouth, etc.

Workaround: Set preference mail.strictly_mime to true.

Note: Multiple spaces or tabs get converted to non-breaking spaces and they get transmitted as 8bit characters which don't get transmitted properly.
