在应用程序上创建 pdf 时，如何设置 mpdf HTML 包含无效的 UTF-8 字符
回答by MoxFulder
Try this
尝试这个
$html = mb_convert_encoding($html, 'UTF-8', 'UTF-8');
before calling: "$mpdf->WriteHTML($html);"
在调用之前：“$mpdf->WriteHTML($html);”
It's seems senseless, but it works for me.
这似乎毫无意义，但它对我有用。

With mpdf it is no point in conversions and encoding as these most likely will lose your chars and you would get only "?" or other unrecognisable chars (but will yield output)
使用 mpdf，转换和编码毫无意义，因为这些很可能会丢失您的字符，而您只会得到“？” 或其他无法识别的字符（但会产生输出）
Try using these before any input being send to mpdf:
在将任何输入发送到 mpdf 之前尝试使用这些：
$mpdf->allow_charset_conversion=true;
$mpdf->charset_in='UTF-8';

The below two lines will do the trick
下面的两行代码可以解决问题
$mpdf->allow_charset_conversion = true;
$mpdf->charset_in = 'iso-8859-4';
Add the above two lines after creating the object , this will look like
创建对象后添加以上两行，这看起来像
$mpdf=new mPDF();
$mpdf->allow_charset_conversion = true;
$mpdf->charset_in = 'iso-8859-4';

After hours of hair-pulling, this worked wonders for me :)
经过几个小时的拉头发，这对我来说很神奇:)
(In my case ??????? was showing as ??????)
（在我的情况下 ??????? 显示为 ??????)
$mpdf->SetAutoFont();
$mpdf->SetAutoFont();
$mpdf = new mPDF('utf-8','', 0, '', 15, 15, 16, 16, 9, 9, 'L');
$mpdf->SetAutoFont();
//~ Nothing of below worked :(
//~ $mpdf->useLang = true;
//~ $mpdf->autoScriptToLang = true;
//~ $mpdf->autoLangToFont = true;
//~ $pdf_html = mb_convert_encoding($html, 'UTF-8', 'UTF-8');
$mpdf->WriteHTML($html);
//~ $mpdf->DeletePages(2);
$filename = date('ymdhis').".pdf";
$mpdf->Output($filename,'D');
My PDF included a mix of English and Hindi words like

I'm 99% sure that problem is because you did some manipulations with the text using unicode-unsafe functions. Use mb_strpos()/mb_substr()instead of strpos()/substr(), and add "/u" modifier to all your conversions with prog_replace().
我 99% 肯定这个问题是因为您使用 unicode-unsafe 函数对文本进行了一些操作。使用mb_strpos()/mb_substr()而不是strpos()/substr()，并使用 将“ /u”修饰符添加到所有转换中prog_replace()。
Of course, the problem can be fixed by allowing "charset conversion" as already suggested before. But much better to know that your text already correct and meets the compliance of UTF-8.
当然，这个问题可以通过允许之前已经建议的“字符集转换”来解决。但最好知道您的文本已经正确并符合 UTF-8 的要求。
