How to set up mpdf?

Question

PHP

Hello.
httpd server 2.4. PHP: 5.6.23. Site on 1C-Bitrix. Runs on UFT-8 (mbstring.func_overload 2).
Downloaded mpdf6. On the page I create a pdf:

$html = 'привет. hello. 123';
require_once $_SERVER['DOCUMENT_ROOT']."/libs/mpdf60/mpdf.php";

$mpdf = new mPDF('utf-8', 'A4', '10', 'Arial');
$mpdf->charset_in = 'utf-8';
$mpdf->WriteHTML($html);
$mpdf->Output();

The output occurs in a downed encoding (krakozyaba). I found in Google that mpdf should be mbstring.func_overload = 0, but this cannot be done, because Bitrix works on mbstring.func_overload = 2.
Please help with a solution.

Answer 1

in .htaccess encoding AddDefaultCharset UTF-8
And resave .php files in the same encoding

Answer 2

I did this:
For the folder in which mpdf is located, set mbstring.func_overload = 0. And Bitrix will still work with mbstring.func_overload = 2

Answer 3

Diversion

<Directory весь сайт> 
        php_admin_value mbstring.func_overload 2
  php_admin_value mbstring.internal_encoding UTF-8 
</Directory> 

<Directory сайт/пусть до mpdf> 
       php_admin_value mbstring.func_overload 0
</Directory>

Answer 4

So is there a solution? I am also struggling with this problem. VDS from timeweb. I write php_admin_value mbstring.func_overload 0 to the apache config file for the mpdf folder. Phpinfo() returns 0 on the directory. But the pdf is never generated. Only there is to set 0 for the entire directory of the site. But Bitrix swears. I ask for help from those who generate pdf using mpdf60 on Bitrix..
