+   The  strpbrk()  function locates the first occurrence in the string s
+   of any of the characters in the string accept and returns a pointer
+   to that character or NULL if not found.
+
+   This method checks the length of accept string. If it fits entirely
+   in one vector register, a fast algorithm is used, which does not need
+   to check multiple parts of accept-string. Otherwise a slower full
+   check of accept-string is used.
