Rolland,
+PHPAPI void php_unify_string_types(zval **p, zval **q TSRMLS_DC)

There is an API function zend_get_best_string_type(). It will figure
out the optimal string type based on the strings passed to it. Then
you can use that optimal type to unify them via
convert_to_explicit_type() function.
+ if (Z_TYPE_PP(str) == IS_UNICODE) {
+ i = 0; str_codepts = 0;
+ while (i < Z_USTRLEN_PP(str)) {
+ U16_FWD_1(Z_USTRVAL_PP(str), i, Z_USTRLEN_PP(str));
+ str_codepts++;
+ }
+ } else {
+ str_codepts = Z_STRLEN_PP(str);
+ }
u_countChar32() again would help.
