Is it ASCII? No.
No.
Does gnus-article-treat-non-ascii treat it?
No.
"It's not Unicode."
That's right. And it also isn't ASCII.
"Well then don't worry about it. They will be caught at the
  Non-printable characters found.  Continue sending? (delete, replace, send, edit, ?):
prompt."

Hey, I never said I want to send anything. I'm talking about just
looking at them.

As you can see, those characters are so terrible, they deserve their own
gnus-article-treat-128-255 !!

If you get raw bytes in your Gnus messages, that usually means that
you're decoding the message incorrectly.  Removing the characters in the
128-255 rarely, in my experience, leads to a material improvement in the
message itself.

If this is a problem you encounter often, then writing a command that
removes these characters should be easy enough.

Closing.
