$pdf->SetFont(‘stsongstdlight’, ”, 20);
早就试了，这个不行，用writerHTML函数不好使
tcpdf 要求中文内容是 utf-8 编码的，而显然你的是 gbk 的帖出乱码的截图是很有必要的，因为他有助于问题的判断，因为乱码的评定标准因人而异如果你不说中文在文件中都是问号，我也无法做出判断，而问号并不是乱码

我怎么知道俊莫 and 春梅毛是 utf-8 编码的？
写到后面的html页面中了，页面设置的utf-8啊
现在就是用的writeHtml函数，怎么弄都是中文变问号，用write没事，但是格式没有
如果 ‘俊莫 and 春梅毛’是 gbk 编码的，你把它声明成 utf-8（<meta charset="utf-8">）的，那么必然导致乱码！
$writer = '俊莫 and 春梅毛';
  $a  = mb_detect_encoding($writer);
p($a);die;
mb_detect_encoding 出现误判是大概率事件
不然也不会再有个 mb_check_encoding 了
mb_check_encoding — Check if the string is valid for the specified encoding说明
bool mb_check_encoding ([ string $var = NULL [, string $encoding = mb_internal_encoding() ]] )
Checks if the specified byte stream is valid for the specified encoding. It is useful to prevent so-called "Invalid Encoding Attack".
参数var
The byte stream to check. If it is omitted, this function checks all the input from the beginning of the request. encoding
The expected encoding.
返回值
成功时返回 TRUE，或者在失败时返回 FALSE.
--------------------------------------------------------------------------------
返回的是true。
$writer = '俊莫 and 春梅毛';
        $a  = mb_check_encoding ($writer);
        p($a);die;
