Support Unicode

Can you please send me an example. It works for me.

I think it's MS Excel not support UTF. And this's huge problem. Could you please support something other character encoding? Or tell me please where I can put encoding function, for example this (for win1251):

function utf2win1251($content)
{
                $newcontent = "";
 
                for ($i = 0; $i < strlen($content); $i++)
                {
                        $c1 = substr($content, $i, 1);
                        $byte1 = ord($c1);
                        if ($byte1>>5 == 6)
                        {
                                $i++;
                                $c2 = substr($content, $i, 1);
                                $byte2 = ord($c2);
                                $byte1 &= 31;
                                $byte2 &= 63;
                                $byte2 |= (($byte1 & 3) << 6);
                                $byte1 >>= 2;
                                $word = ($byte1<<8) + $byte2;
 
                                if ($word == 1025) $newcontent .= chr(168);
                                else if ($word == 1105) $newcontent .= chr(184);
                                else if ($word >= 0x0410 && $word <= 0x044F) $newcontent .= chr($word-848);
                                else
                                {
                                        $a = dechex($byte1);
                                        $a = str_pad($a, 2, "0", STR_PAD_LEFT);
                                        $b = dechex($byte2);
                                        $b = str_pad($b, 2, "0", STR_PAD_LEFT);
                                        $newcontent .= "?".$a.$b.";";
                                }
                        }
                        else
                                $newcontent .= $c1;
                }
 
        return $newcontent;
}

I am trying to export fields that got french caracters (with accent) and this does not work. Could you help me to do this ? Thanx

Now with utf8 support.
