With regard to special characters, I have yet to see a degree sign
come through the NAFEX list without turning into a question mark, but
here's my try anyway. Please let me know how it turns out:
98°F
Showed up here as: 98°F
that is, nine eight ampersand poundsign one seven six semicolon F
I don't know how much of the problem is the NAFEX list, though; I think it may be different email programs. My degree sign ยบ comes through NAFEX and back to me just fine; but someone apparently reported it as having turned into something else. If the problem were the list, I would think it would also come back to me garbled.
