Encoding

In Utf8, character 子 (X5B50) is encoded with 3 bytes. These bytes are:
xE5 xAD x90 in the hexadecimal representation and
229 173 144 in the decimal representation.

In HTML, this character can be generated with
& # X 5 B 5 0 ; and also with
& # 1 2 0 7 0 ;
For activation, the spaces should be removed from the two lines above; then, each of them generates the same character X2F26 (⼦ ⼦).

Encoding of ⼦ and that of the similar character 子 can be revealed with the PHP program below:

<?php 
function unichr($dec) {
  if ($dec < 128) {
    $utf = chr($dec);
  } else if ($dec < 2048) {
    $utf = chr(192 + (($dec - ($dec % 64)) / 64));
    $utf .= chr(128 + ($dec % 64));
  } else {
    $utf = chr(224 + (($dec - ($dec % 4096)) / 4096));
    $utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64));
    $utf .= chr(128 + ($dec % 64));
  }
  return $utf;
} 

function mb_str_split($str) {
   // split multibyte string in characters
   // at all positions except the start: ^
   // and the end: $
   $pattern = '/(?<!^)(?!$)/u';
   return preg_split($pattern,$str);
}

function uniord($a) 
{
  $M=strlen($a);
  $p=ord($a[0]);                    if($M==1) return $p;
  $p-=194;  $p*=64; $p+=ord($a[1]); if($M==2) return $p;
  $p-=2050; $p*=64; $p+=ord($a[2]);           return $p;
}

//$a=unichr(0x2f25);
//$a.=unichr(0x5973);
//$a.=unichr(0xF981);

$a="⼦子";
echo "$a\n";
$N=strlen($a);
echo "The array has $N bytes; here is its splitting:\n";

for($n=0;$n<$N;$n++)
{
printf("%02x ",ord($a[$n]) );
}
echo "\n";

$b = mb_str_split($a);

var_dump($b);
$M=count($b);

#mb_internal_encoding("UTF-8");

for($m=0;$m<$M;$m++)
{
printf("\n");
$c=$b[$m];
$u=uniord($c);
printf("Unicode character number %05d id est, [[X%04X]]\n",$u,$u);
$d=strlen($c);
echo "Picture: [[$c]] ; uses $d bytes. These bytes are:\n";
for($n=0;$n<$d;$n++) printf("x%2X ",ord($c[$n]));
printf("in the hexadecimal representation and\n");
for($n=0;$n<$d;$n++) printf("%3d ",ord($c[$n]));
printf("in the decimal representation\n");
}
?>

This program uses the portable PHP functions unichr.t, mb_str_split.t, uniord.t.
