I am having problems with getting the right output of the invoice PDF. Instead of getting letters such as 'łóś" I am getting "?" marks printed.
I have tried several font options in Configuration->Invoice-> PDF Fonts without success. I have downloaded tcpdf fonts from Github and put them into /com_eshop/tcpdf/font directory but testing other font options didn't gave me the result I was looking for.
By quick looking into the php sources it looks like the data transferred in between eshop and tcpdf should be UTF-8 formatting, which shall ensure proper font conversion.
Please enlighten me how do I get the right output? I am kinda stuck at the moment.
The reason because the font for your language is missing from the settings of EShop. Please submit a new ticket to EShop category to send me the super admin account to your site there so I can help you to check and configure it properly for you.
