The 'ignore' option will simply drop the character which cannot
be encoded (e.g. because there is no mapping for the Unicode
character in the chosen character set), the 'replace' option
will currently always write a '?' instead of the Unicode character
which caused the trouble.

Latin-1 is not the same as the default Windows encoding which
typically is one of the cp125x encodings depending on your locale.
That could be the cause of the ValueErrors you are seeing.
