PHP resolves html class library simple_html_Transcoding bug from dom

simple_is in use these dayshtml_dom grabs a few articles.The codes of different websites are essentially gbk gb2312 utf-8 in China.Most of them were gb2312 and utf-8.

My version of simple_html_dom has a method convert_This is how text looks.

 // PaperG - Function to convert the text from one character set to another if the two sets are not the same.
 function convert_text($text)
 {
  global $debug_object;
  if (is_object($debug_object)) {$debug_object->debug_log_entry(1);}
  $converted_text = $text;
  $sourceCharset = "";
  $targetCharset = "";
  if ($this->dom)
  {
   $sourceCharset = strtoupper($this->dom->_charset);
   $targetCharset = strtoupper($this->dom->_target_charset);
  }
  if (is_object($debug_object)) {$debug_object->debug_log(3, "source charset: " . $sourceCharset . " target charaset: " . $targetCharset);}
  if (!empty($sourceCharset) && !empty($targetCharset) && (strcasecmp($sourceCharset, $targetCharset) != 0))
  {
   // Check if the reported encoding could have been incorrect and the text is actually already UTF-8
   if ((strcasecmp($targetCharset, 'UTF-8') == 0) && ($this->is_utf8($text)))
   {
    $converted_text = $text;
   }
   else
   {
    $converted_text = iconv($sourceCharset, $targetCharset, $text);
   }
  }
  // Lets make sure that we don't have that silly BOM issue with any of the utf-8 text we output.
  if ($targetCharset == 'UTF-8')
  {
   if (substr($converted_text, 0, 3) == "\xef\xbb\xbf")
   {
    $converted_text = substr($converted_text, 3);
   }
   if (substr($converted_text, -3) == "\xef\xbb\xbf")
   {
    $converted_text = substr($converted_text, 0, -3);
   }
  }
  return $converted_text;
 }

Look at this line:

    $converted_text = iconv($sourceCharset, $targetCharset, $text);  

This will cause incorrect transcoding.For example, the text of gb2312 would be converted to:

4 month 26 Day in <span style="color:#C03"> Collateral </span> At the Park Equestrian Range 2014 In the qualifying match of the Chinese Langqin International Horse Federation Stadium Barrier World Cup, 24 Han Zhuangzhuang, aged 18, not only scored a zero penalty  ... No. 7 Of them <span style="color:#C03"> Contains </span> Olympic Rider Zhao Zhiwen Di 1 Zero penalties per harvest, time consuming 77 second 07 ...

It is a fact that the transcoding function inside is not handled properly.Because I use this simple_html_dom just wanted to build dom.I don't intend to spend time doing a good job with this bug.But simply

$converted_text = iconv($sourceCharset, $targetCharset, $text); 

Change to

$converted_text = $text; 

That's it.The idea is to cancel its transcoding.Okay, work doesn't have to be tangled, it can go on.
