*NULL* if an exception was raised by the codec.
+UTF-7 Codecs
+""""""""""""
+
+These are the UTF-7 codec APIs:
+
+
+.. cfunction:: PyObject* PyUnicode_DecodeUTF7(const char *s, Py_ssize_t size, const char *errors)
+
+ Create a Unicode object by decoding *size* bytes of the UTF-7 encoded string
+ *s*. Return *NULL* if an exception was raised by the codec.
+
+
+.. cfunction:: PyObject* PyUnicode_DecodeUTF8Stateful(const char *s, Py_ssize_t size, const char *errors, Py_ssize_t *consumed)
+
+ If *consumed* is *NULL*, behave like :cfunc:`PyUnicode_DecodeUTF7`. If
+ *consumed* is not *NULL*, trailing incomplete UTF-7 base-64 sections will not
+ be treated as an error. Those bytes will not be decoded and the number of
+ bytes that have been decoded will be stored in *consumed*.
+
+
+.. cfunction:: PyObject* PyUnicode_EncodeUTF7(const Py_UNICODE *s, Py_ssize_t size, int base64SetO, int base64WhiteSpace, const char *errors)
+
+ Encode the :ctype:`Py_UNICODE` buffer of the given size using UTF-7 and
+ return a Python bytes object. Return *NULL* if an exception was raised by
+ the codec.
+
+ If *base64SetO* is nonzero, "Set O" (punctuation that has no otherwise
+ special meaning) will be encoded in base-64. If *base64WhiteSpace* is
+ nonzero, whitespace will be encoded in base-64. Both are set to zero for the
+ Python "utf-7" codec.
