58cf607d13 Issue #12892: The utf-16* and utf-32* codecs now reject (lone) surrogates. 
The utf-16* and utf-32* encoders no longer allow surrogate code points
(U+D800-U+DFFF) to be encoded.
The utf-32* decoders no longer decode byte sequences that correspond to
surrogate code points.
The surrogatepass error handler now works with the utf-16* and utf-32* codecs.

Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.

8b097b4ed7 Close #17828: better handling of codec errors 
- output type errors now redirect users to the type-neutral
  convenience functions in the codecs module
- stateless errors that occur during encoding and decoding
  will now be automatically wrapped in exceptions that give
  the name of the codec involved

602f7cf0b9 Issue #19424: Optimize PyUnicode_CompareWithASCIIString()

strlen() is still necessary to check Unicode string containing null bytes.

fa3ba4c3bc Issue #18609: Add a fast-path for "iso8859-1" encoding 
On AIX, the locale encoding may be "iso8859-1", which was not a known syntax of
the legacy ISO 8859-1 encoding.

Using a C codec instead of a Python codec is faster but also avoids tricky
issues during Python startup or complex code.
