Heinz, bug #58206 has now been fixed.  If you're able, please test the fix by grabbing the latest tmac/pdfpic.tmac from git (this file has had some other cleanup done to it as well) to make sure it solves the problem you were seeing.  Thanks!

Turns out bug #58206 was already open to address this.  Further discussion should be redirected there.

Heinz, you've probably tested the various proposed solutions more than anyone -- do you have a preference between the awk command (posted at http://lists.gnu.org/archive/html/groff/2021-09/msg00061.html) and the sed one (posted at http://lists.gnu.org/archive/html/groff/2021-09/msg00062.html)?

As discussed on the email list (http://lists.gnu.org/archive/html/groff/2021-09/msg00046.html), tmac/pdfpic.tmac contains an external (.sy) call to a shell pipeline that includes a grep command which fails in cases where it falsely detects its input stream to be binary.  Further down the thread, a sed and an awk command are both proposed as more robust replacements for the grep.

Addressing bug #55107 will obviate the need for this shell pipeline at all.  This is the preferred fix for this problem.  But it's a more substantial change, and the fix proposed in the aforementioned email thread is simple and low-risk, so it's something that could be done until 55107 is addressed.
