	      $char_A_ring = "xC3x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
	      $char_combining_ring_above = "xCCx8A";	// 'COMBINING RING ABOVE' (U+030A)

	      $char_orig = 'A' . $char_combining_ring_above;
	      $char_norm = normalizer_normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

	      echo ( normalizer_is_normalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      echo '; ';
	      echo ( normalizer_is_normalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      ?>

       Example #2

	      OO example

	      <?php
	      $char_A_ring = "xC3x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)

	      $char_orig = 'A' . $char_combining_ring_above;
	      $char_norm = Normalizer::normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

	      echo ( Normalizer::isNormalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      echo '; ';
	      echo ( Normalizer::isNormalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
