STINNER Victor <[email protected]> added the comment:
The example raises an AssertionError(u'\n- \ufffd+ \ufffd\ufffd') which is
converted to string by traceback.format_exception(). This function fails in
_some_str() on str(value) instruction. You can reproduce the error with:
>>> str(AssertionError(u"\xe9"))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0:
ordinal not in range(128)

The problem is not related to the terminal encoding: str(value) uses Python
default encoding (ASCII by default). Python3 is not concerned because
str(AssertionError("\xe9")) doesn't raise any error: it returns "\xe9".
