    In Unicode, "And" will be "1048", and "A" - "1040", where did you get these codes from?

    Here is the working conversion function (taken from php.net):

     function uniord($ch) { $n = ord($ch{0}); if ($n < 128) { return $n; // no conversion required } if ($n < 192 || $n > 253) { return false; // bad first byte || out of range } $arr = array(1 => 192, // byte position => range from 2 => 224, 3 => 240, 4 => 248, 5 => 252, ); foreach ($arr as $key => $val) { if ($n >= $val) { // add byte to the 'char' array $char[] = ord($ch{$key}) - 128; $range = $val; } else { break; // save some e-trees } } $retval = ($n - $range) * pow(64, sizeof($char)); foreach ($char as $key => $val) { $pow = sizeof($char) - ($key + 1); // invert key $retval += $val * pow(64, $pow); // dark magic } return $retval; }
    • The author indicated the codes in the 16-tric system - yozh
    • Very strange code. For the characters Ё, Ё, yu, and I in cp-1251, return false . Decimal codes CP1251 A: 192 ... e: 253 S: 254 I: 255 S: 184 Y: 168 - avp
    • so it is 1251, but you need Unicode - DemoS
    • As I understand it, the parameter of the function uniord ($ ch) is a character in cp1251, and its result is a character in Unicode. Is not it ? - avp
    • Well, so what, returns in Unicode, that's right. And what have your codes in cp1251? - DemoS
