New submission from Eric Snow:
I'm guessing this is a very seldom (never?) used code path. I've included a
patch to test and fix the problem. The patch includes several related tests
for pydoc.
$ py3 -c 'import pydoc;
pydoc.synopsis("/opt/python3.4/lib/python3.4/lib-dynload/time.cpython-34m.so")'
Traceback (most recent call last):
File "/opt/python3.4/lib/python3.4/tokenize.py", line 368, in find_cookie
line_string = line.decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf4 in position 96:
invalid continuation byte
During handling of the above exception, another exception occurred:
