possible. This macro does not raise exceptions.
These APIs can be used to work with surrogates:
.. c:macro:: Py_UNICODE_IS_SURROGATE(ch)
Check if *ch* is a surrogate (``0xD800 <= ch <= 0xDFFF``).
.. c:macro:: Py_UNICODE_IS_HIGH_SURROGATE(ch)
Check if *ch* is an high surrogate (``0xD800 <= ch <= 0xDBFF``).
.. c:macro:: Py_UNICODE_IS_LOW_SURROGATE(ch)
Check if *ch* is a low surrogate (``0xDC00 <= ch <= 0xDFFF``).
.. c:macro:: Py_UNICODE_JOIN_SURROGATES(high, low)
Join two surrogate characters and return a single Py_UCS4 value.
*high* and *low* are respectively the leading and trailing surrogates in a
surrogate pair.
