解决办法1：

由于GD库编译时添加了: --enable-gd-jis-conv    的支持(   GD: Enable JIS-mapped Japanese font ) , 在phpinfo()里也可以看到:JIS-mapped Japanese Font Support的支持为enable，需要重新编译PHP，在编译PHP时，去掉 --enable-gd-jis-conv即可

去掉编译选项“--enable-gd-jis-conv”

 

关闭GD库中 “JIS-mapped Japanese Font Support”

贴上官方的解释：

There is no fallback ot UTF-8. It accepts UTF-8 by default. The problem

about JIS is when you pass a non UTF-8 string, it can be seen as JIS

enconded string.

About the mbstring issues, I have no idea how it works and how it

affects the input parameters. It is something happening before we got

the hand in the gd function.

解决办法2：

mb_convert_encoding($markWords,"html-entities","UTF-8")

 

/**

* 将文本由UTF8编码转化为数字形式编码(HTML实体)

* @param $arr 该参数可以为数组或者string

* @author Steven lxq70361@qq.com

*/ 

function iconv_arr($arr){ 

if(is_array($arr)){

   foreach($arr as $k=>$v){

    $arr[$k] = iconv_arr($v);

   }

   

}else{

   $arr = mb_convert_encoding($arr, "html-entities","utf-8" );

}

return $arr;

}

?>
