Android Question string to UTF16 = PHP?

[Tayfur]

I have some codes with PHP;

function _UTF8toUTF16($s)
{
    // UTF-8 to UTF-16BE with BOM
    $res = "\xFE\xFF";
    $nb = strlen($s);
    $i = 0;
    while($i<$nb)
    {
        $c1 = ord($s[$i++]);
        if($c1>=224)
        {
            // 3-byte character
            $c2 = ord($s[$i++]);
            $c3 = ord($s[$i++]);
            $res .= chr((($c1 & 0x0F)<<4) + (($c2 & 0x3C)>>2));
            $res .= chr((($c2 & 0x03)<<6) + ($c3 & 0x3F));
        }
        elseif($c1>=192)
        {
            // 2-byte character
            $c2 = ord($s[$i++]);
            $res .= chr(($c1 & 0x1C)>>2);
            $res .= chr((($c1 & 0x03)<<6) + ($c2 & 0x3F));
        }
        else
        {
            // Single-byte character
            $res .= "\0".chr($c1);
        }
    }
    return $res;
}

I serched an convert PHP code . And My B4a code is:

Sub UTF8toUTF16(data As String) As String
    Dim bb() As Byte
    bb=data.GetBytes("UTF16")
    Return BytesToString(bb,0,bb.Length,"UTF16")
End Sub

My questions is myB4A code return same PHP return data??

Your B4A code doesn't do anything useful.
String variables do not have any encoding.

Encoding is only relevant when you want to convert a string object to bytes or from bytes to a string object.

What do you need to do? What is the input and what is the output?

output values for special file format. after I wirete directly a file. (I have only php code)

 

[Erel]

You can use TextWriter to save a string to a file in any encoding you like.

 

[Tayfur]

can I do wtih like sample php code

PHP >> chr() B4A>>chr () is it same?
PHP >> ord() B4A>>??

 

[Erel]

You don't need it. Let TextWriter do the job for you.
