And opening binary file without "b" option is very common mistake of new developers. If default error handler is surrogateescape, they lose a chance to notice their bug.

To come back to your original point, I didn't know that it was a common mistake to open binary files in text mode.

Honestly, I didn't try recently. How does Python behave when you do that?

Is it possible to write a full binary parser using the text mode? You should quickly get issues pointing you to your mistake, no?
