To extract hiragana, katakana, kanji portion of a Japanese text, explicity set the unicode range AND
specify u modifier for the pattern.
<?
echo "Hiragana -- ";
$pattern ='/[^\x{3040}-\x{309F}]+/u';
$s=preg_replace($pattern,"",$str);
echo $s."<br />";
echo "Katakana -- ";
$pattern ='/[^\x{30A0}-\x{30FF}]+/u';
$s=preg_replace($pattern,"",$str);
echo $s."<br />";
echo "Kanji -- ";
$pattern ='/[^\x{4E00}-\x{9FBF}]+/u';
$s=preg_replace($pattern,"",$str);
echo $s."<br />";
