+Subject: [PATCH] Fix syntax error test for Python 3.9
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On Python 3.9 the zero-width no-break space Unicode character U+FEFF
+does not get printed in syntax errors.
+
+See:
+https://bugzilla.redhat.com/show_bug.cgi?id=1831126
+
+This is reproducible in a virtual environment as well.
+
+Before:
+```
