I downloaded all plugin files via ftp and changed UTF-8 everywhere to ISO-8895-2 in Notepad++. There were almost 500 of them, but it changed anything 😥

Oh no!! That is a huge mistake and as you've learned it has nothing to do with your problem. I hope you have a way of restoring your site and put all the plugins back to their correct state. Since WordPress 4.2 the the defaults established for DB Collation and character set has been utf8mb4 and utf8mb4_unicode_520_ci. This combination supports every known language.

The problem you're running into with the PDF has nothing to do with the database collation and character set. The default fonts for PDF generation do not support an extended characters. You need to change the PDF's font to support your language.

I tried to change font for Arial, but it still doesn't work... 😥 I tried to make it by adding snippet below and edit font-family in css files...

add_filter('frm_data', 'custom_font_pdfs_css', 10, 2);
function custom_font_pdfs_css( $css, $args ) {
$custom_css = 'body { font-family: Arial; }';
return $css . $custom_css;
}

Could we contact on e-mail - maybe you can take a look on my website? 😥
