fopen无法读取阿拉伯字符

Question

此函数读取（document.doc）文件..但它将阿拉伯字符变成英文字符

我想让它读成阿拉伯字符，或至少删除它。

    function word($filename){ 


    if(($fh = fopen($filename, 'r')) !== false ) { 

       $headers = fread($fh, 0xA00); 
       $n1 = ( ord($headers[0x21C]) - 1 ); 
       $n2 = ( ( ord($headers[0x21D]) - 8 ) * 256 ); 
       $n3 = ( ( ord($headers[0x21E]) * 256 ) * 256 ); 
       $n4 = ( ( ( ord($headers[0x21F]) * 256 ) * 256 ) * 256 ); 
       $textLength = ($n1 + $n2 + $n3 + $n4); 
       if($extracted_plaintext = @fread($fh, $textLength)){ 

       }else{ 
            return docx2text($filename); // Save this contents to file 
       } 

        $text=str_replace(  chr(13) , "\n", $extracted_plaintext); 

        echo $text; 
    } 


} 

word('filename.doc');  

E.X：filename.doc - ＆gt;文件包含语句“بسماللهالرحمنالرحيم”
