process_operation raises "TypeError: a bytes-like object is required, not 'dict'" #953
Description
When I try to extrac the text from the PDF below, I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/moose/Github/py-pdf/PyPDF2/PyPDF2/_page.py", line 1263, in extract_text
return self._extract_text(self, self.pdf, space_width, PG.CONTENTS)
File "/home/moose/Github/py-pdf/PyPDF2/PyPDF2/_page.py", line 1245, in _extract_text
process_operation(operator, operands)
File "/home/moose/Github/py-pdf/PyPDF2/PyPDF2/_page.py", line 1197, in process_operation
text += operands[0].translate(cmap)
TypeError: a bytes-like object is required, not 'dict'
Fixing this issue would likely also fix #523
