   --  Decode a byte string from the locale encoding with the surrogateescape
   --  error handler: undecodable bytes are decoded as characters in range
   --  U+DC80..U+DCFF. If a byte sequence can be decoded as a surrogate
   --  character, escape the bytes using the surrogateescape error handler
   --  instead of decoding them.

   --  Encoding, highest priority to lowest priority:
   --    * UTF-8 on macOS, Android, and VxWorks;
   --    * UTF-8 on Windows if Py_LegacyWindowsFSEncodingFlag is zero;
   --    * UTF-8 if the Python UTF-8 mode is enabled;
   --    * ASCII if the LC_CTYPE locale is "C", nl_langinfo(CODESET) returns
   --      the ASCII encoding (or an alias), and mbstowcs() and wcstombs()
   --      functions uses the ISO-8859-1 encoding.
   --    * the current locale encoding.

   --  Return a pointer to a newly allocated wide character string, use
   --  PyMem_RawFree() to free the memory.

   --  Raise DecodingError or MemoryError in case of error

   --  Decoding errors should never happen, unless there is a bug in the C
   --  library.
