For encoding *error_handler* will be called with a :exc:`UnicodeEncodeError`
- instance, which contains information about the location of the error. The error
- handler must either raise this or a different exception or return a tuple with a
- replacement for the unencodable part of the input and a position where encoding
- should continue. The encoder will encode the replacement and continue encoding
- the original input at the specified position. Negative position values will be

Decoding and translating works similar, except :exc:`UnicodeDecodeError` or
:exc:`UnicodeTranslateError` will be passed to the handler and that the
