Confusion

Picture of character 大 may look similar to that of character ⼤;
⼤ (& # x 2 F 2 4 ;)
⼤ (& # 1 2 0 6 8 ;)
that may have similar pronunciation and meaning, "big".

Such a similarity may lead to confusions. For databases,
大 (大 (& # x 5 9 2 7 ;)) and
⼤ (⼤ (& # x 2 F 2 4 ;))
are two different Unicode characters.

This confusion can be illustrated with the code below:

<?php
function mb_str_split($str) {
   // split multibyte string in characters
   // Split at all positions, not after the start: ^
   // and not before 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='⼤ 大'; # two different unicode characters separated with spacebar

$N=strlen($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");
}
?>

Functions mb_str_split.t and uniord.t are used in the code above.

The output:

The array has 7 bytes; here is its splitting:
e2 bc a4 20 e5 a4 a7 
array(3) {
  [0]=>
  string(3) "⼤"
  [1]=>
  string(1) " "
  [2]=>
  string(3) "大"
}
