note 70776 added to function.utf8-decode

I noticed that the utf-8 to html functions below are only for 2 byte long codes. Well I wanted 3 byte support (sorry haven't done 4, 5 or 6). Also I noticed the concatination of the character codes did have the hex prefix 0x and so failed with the large 2 byte codes) <? public function utf2html (&$str) { $ret = ""; $max = strlen($str); $last = 0; // keeps the index of the last regular character for ($i=0; $i<$max; $i++) { $c = $str{$i}; $c1 = ord($c); if ($c1>>5 == 6) { // 110x xxxx, 110 prefix for 2 bytes unicode $ret .= substr($str, $last, $i-$last); // append all the regular characters we've passed $c1 &= 31; // remove the 3 bit two bytes prefix $c2 = ord($str{++$i}); // the next byte $c2 &= 63; // remove the 2 bit trailing byte prefix $c2 |= (($c1 & 3) << 6); // last 2 bits of c1 become first 2 of c2 $c1 >>= 2; // c1 shifts 2 to the right $ret .= "&#" . ($c1 * 0x100 + $c2) . ";"; // this is the fastest string concatenation $last = $i+1; } elseif ($c1>>4 == 14) { // 1110 xxxx, 110 prefix for 3 bytes unicode $ret .= substr($str, $last, $i-$last); // append all the regular characters we've passed $c2 = ord($str{++$i}); // the next byte $c3 = ord($str{++$i}); // the third byte $c1 &= 15; // remove the 4 bit three bytes prefix $c2 &= 63; // remove the 2 bit trailing byte prefix $c3 &= 63; // remove the 2 bit trailing byte prefix $c3 |= (($c2 & 3) << 6); // last 2 bits of c2 become first 2 of c3 $c2 >>=2; //c2 shifts 2 to the right $c2 |= (($c1 & 15) << 4); // last 4 bits of c1 become first 4 of c2 $c1 >>= 4; // c1 shifts 4 to the right $ret .= '&#' .
