Documentation

The are a couple of paragraphs about error-checking behaviour for str.encode and str.decode that appears in a few versions of Python and could potentially be improved in future versions.

As found in the Python 3.9.14 documentation for std.encode:

By default, the errors argument is not checked for best performances, but only used at the first encoding error. Enable the Python Development Mode, or use a debug build to check errors.

The paragraph before that is fairly dense - there could be an opportunity to improve both of them.
