Not really related to your change, but please get rid of the alignment here, it doesn't work with tabs.

foobar(
    foo, bar)
// instead of
foobar(foo,
       bar)

To avoid code-size increase, let's move this common parameter parsing code into a function. Maybe something like

static zend_never_inline int parse_code_point_param(UChar32 *cp) {
    zend_string *string_codepoint;
    zend_long int_codepoint;
    ZEND_PARSE_PARAMETERS_START(1, 1)
        Z_PARAM_STR_OR_LONG(string_codepoint, int_codepoint)
    ZEND_PARSE_PARAMETERS_END_EX(return FAILURE);
    return convert_cp(cp, string_codepoint, int_codepoint);
}

Will also simplify the code in places.
