php配置GD后显示的参数，能告诉我这样能生成中文的图形吗？

部分代码：
在显示的地方使用
include("gb2utf8.php";
$str=gb2utf8("『嘉善在线』即时地图服务";
ImageTTFText($map_img,20,0,5,25,$color2,"simhei.ttf",$str);




<?

//Program writen by sadly www.phpx.com

function gb2utf8($gb)
{
if(!trim($gb))
return $gb;
$filename="gb2312.txt";
$tmp=file($filename);
$codetable=array();
while(list($key,$value)=each($tmp))
$codetable[hexdec(substr($value,0,6))]=substr($value,7,6);

$utf8="";
while($gb)
{
if (ord(substr($gb,0,1))>;127)
{
$this=substr($gb,0,2);
$gb=substr($gb,2,strlen($gb));
$utf8.=u2utf8(hexdec($codetable[hexdec(bin2hex($this))-0x8080]));
}
else
{
$gb=substr($gb,1,strlen($gb));
$utf8.=u2utf8(substr($gb,0,1));
}
}

$ret="";
for($i=0;$i<strlen($utf;$i+=3)
$ret.=chr(substr($utf8,$i,3));

return $ret;
}

function u2utf8($c)
{
for($i=0;$i<count($c);$i++)
$str="";
if ($c < 0x80) {
$str.=$c;
}
else if ($c < 0x800) {
$str.=(0xC0 | $c>;>;6);
$str.=(0x80 | $c & 0x3F);
}
else if ($c < 0x10000) {
$str.=(0xE0 | $c>;>;12);
$str.=(0x80 | $c>;>;6 & 0x3F);
$str.=(0x80 | $c & 0x3F);
}

$str.=(0xF0 | $c>;>;1;
$str.=(0x80 | $c>;>;12 & 0x3F);
$str.=(0x80 | $c>;>;6 & 0x3F);
