	      $char_a_ring_nfd = "axCCx8A";  // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D"
	      $char_o_diaeresis_nfd = "oxCCx88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"

	      print grapheme_strlen( 'abc' . $char_a_ring_nfd . $char_o_diaeresis_nfd . $char_a_ring_nfd);
