Summary: errors=ignore broken on StreamWriter?

Initial Comment:
Hi,

when writing wrong-encoded characters to a StreamWriter
I get a UnicodeDecodeError. The question is why
errors="ignore" is not working in this case since there
is an exception raised.

Attached is the script that produced the error.

The problem is in your example: 'ä' is an 8-bit string
which is passed to the codec's .encode() method.
Because the Latin-1 codecs expects Unicode as input
to .encode(), Python tries to convert 'ä' to Unicode
assuming it is ASCII - this fails with the exception you
are seeing.

Example:

>>> 'ä'.encode('latin-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in
position 0: ordinal not in range(128)
