In Python 3.5.4 and 3.6.2, both on Windows and Linux, parsing a manifestly correct xml file like:
xml.etree.ElementTree.parse('bad_file.xml')
raises:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 1023: invalid continuation byte
Any other Python version I tried works fine, including 2.7.13, 3.5.2 ...

Simpler reproducer: >>> import xml.etree.ElementTree >>> xml.etree.ElementTree.XML(b'<key attr="' + b'x'*1023 + b'\xc3\xa0""/>') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/serhiy/py/cpython/Lib/xml/etree/ElementTree.py", line 1315, in XML parser.feed(text) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 1023: invalid continuation byte Seems this is a regression in the Expat library. |

This is a duplicate of issue31170. Updating expat to 2.2.4 fixes this issue. |
