This is called a "MIME word" or "MIME encoded word" Mail headers are
supposed to be 7-bit clean even when mail bodies can have 8-bit
encodings. MIME words exist to put quoted-printable and base64 in
headers.

That one is rather mangled. It doesn't follow the =?%s?%c?%s?= format.

That may have been just a copy/paste error; =?U may have got dropped.

It also has a high-bit character in the content.

The originally posted data had an ASCII single quote (not an accent);
may have got changed by the newsreader on reply.

Wouldn't the following work...?

  =?UTF-8?q?They're_telling_us_something_about_something_ok?

But it does show the
quirk of MIME word quoted-printable: underscores used for spaces.

thinks Günter probably likes his name with the accent and not "pure ASCII"

(Not surprising for people with names that contain non-ASCII characters
to have their names represented correctly.)
