STINNER Victor added the comment: The HTML output contains an encoding in the <head>: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
The problem is that sys.stdout may use a different encoding. For example, my locale encoding is UTF-8. So "python -m difflib -um a.py b.py > test.html" produces an HTML file encoded in UTF-8 but announcing a ISO 8859-1 header. There are different options to fix this issue: * drop the --html command line option * drop the invalid Content-Type header * add an option to write the diff into a file, use UTF-8 to encode this file and emit a correct HTTP header (announce UTF-8) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21027> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
