New submission from Dave Challis:
This occurred when attempting to decode invalid UTF-8 bytes using
"errors='replace'", then attempting to lowercase the produced unicode string.
This was also tested in python 2.7, but it doesn't occur there.
Code to reproduce:
x =
b'\xe2\xb3\x99\xb3\xd1\x9f\xe0vjGd|\x12\xf2\x84\xac\xae&$\xa4\xae+\xa4sbtf$&fG\xfb\xe6?.\xe2sbv\x14\xcb\x89\x98\xda\xd9\x99\xda\xb9d9\x1bY\x99\xb7\xb3\x1b9\xa2y*B\xa3\xba\xefj&g\xe2\x92Et\x85~\xbf\x8a\xe3\x919\x8bvc\xfb#$$.\xber6D&b.#4\xa4.\x13RtI\x10\xed\x9c\xd0\x98\xb8\x18\x91\x99\\\nC\x13\x8dV\xccL\xf4\x89\x9c\x90'
x = x.decode('utf-8', errors='replace')
x.lower()
Output:
