I'm trying to make my first post to this forum, but every time I try I get the message:
The message contains invalid characters.
But, there's no indication of which characters are invalid?
I copied the entire message into BBEdit with invisibles displayed and I can't see anything but normal characters. I tried BBEdit's Zap Gremlins, but it found nothing to Zap.
How can I figure out just what characters are invalid?
