JPGraph中文乱码问题

JPGraph处理有中文字符时都会转成utf8编码后显示，我们只需注释掉相关的代码就可以了。

Dotproject苷特图中文乱码解决具体步骤如下：

1。修改jpgraph库

打开dotproject /lib/jpgraph/jpgraph/src/jpgraph.php文件，找到下面代码段

    function Convert($aTxt,$aFF) {
 if( LANGUAGE_CYRILLIC ) {
     if( CYRILLIC_FROM_WINDOWS ) {
  $aTxt = convert_cyr_string($aTxt, "w", "k");
     }
     $isostring = convert_cyr_string($aTxt, "k", "i");
     $unistring = LanguageConv::iso2uni($isostring);
     return $unistring;
 }/* 注释掉下面代码段
 elseif( $aFF === FF_SIMSUN ) {
     // Do Chinese conversion
     if( $this->g2312 == null ) {
  include_once 'jpgraph_gb2312.php' ;
  $this->g2312 = new GB2312toUTF8();
     }
     return $this->g2312->gb2utf8($aTxt);
 }
 elseif( $aFF === FF_CHINESE ) {
     if( !function_exists('iconv') ) {
  JpGraphError::Raise('Usage of FF_CHINESE (FF_BIG5) font family requires that your PHP setup has the iconv() function. By default this is not compiled into PHP (needs the "--width-iconv" when configured).');
     }
     return iconv('BIG5','UTF-8',$aTxt);
 }注释到此结束*/
 else
     return $aTxt;
    }

2.修改dotproject中用到jpgraph的模块

  a.  改project模块

打开dotproject/modules/projects/gantt.php文件，修改文件中下面的代码

将所有

arialbd.ttf

用

simsum.ttc

替换

将所有

FF_ARIAL

用

FF_SIMSUN

替换

注释掉下面的代码

 //if ( $locale_char_set=='utf-8' && function_exists("utf8_decode") ) {
 // $name = utf8_decode($name);
 //}

b.同理修改dotproject/modules/tasks/gantt.php文件
