+Locale Encoding

+The current locale encoding can be used to decode text from the operating

+.. c:function:: PyObject* PyUnicode_DecodeLocaleAndSize(const char *str, Py_ssize_t len, int surrogateescape)
+
+   Decode a string from the current locale encoding. The decoder is strict if
+   *surrogateescape* is equal to zero, otherwise it uses the
+   ``'surrogateescape'`` error handler (:pep:`383`) to escape undecodable
+   bytes. If a byte sequence can be decoded as a surrogate character and
+   *surrogateescape* is not equal to zero, the byte sequence is escaped using
+   the ``'surrogateescape'`` error handler instead of being decoded.  *str*
+   must end with a null character but cannot contain embedded null character.
+
+   .. seealso::
+
+      Use :c:func:`PyUnicode_DecodeFSDefaultAndSize` to decode a string from
+      :c:data:`Py_FileSystemDefaultEncoding` (the locale encoding read at
+      Python startup).

+   length using :c:func:`strlen`.
