"\xC3\x85"// 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
$char_combining_ring_above "\xCC\x8A";  // 'COMBINING RING ABOVE' (U+030A)

$char_orig 'A' $char_combining_ring_above;
$char_norm Normalizer::normalize'A' $char_combining_ring_aboveNormalizer::FORM_C );
 
echo ( 
Normalizer::isNormalized($char_origNormalizer::FORM_C) ) ? "normalized" "not normalized";
echo 
'; ';
echo ( 
Normalizer::isNormalized($char_normNormalizer::FORM_C) ) ? "normalized" "not normalized";
