convert unity byte array to flash string problem

I convert a byte array to a string in Unity this way ( data is a string, bs is a byte array ) :

data+= (char)bs;

Export to Flash, it becomes:

$data = $data + int(int($bs.elements[$i]));

So that, a byte becomes a number based string not a single char.

 

I have solved my problem, just use a flash function to replace C# conversion:

FLASH AS3 code:
public static function codeToChar( code : String):String{
return String.fromCharCode(code);
}

In Unity:

data+= codeToChar( bs.ToString() );

 

you could solve it by casting to string instead to cast to char.
