Getting "?" symbol when using Registration Tags, example [TOTAL_AMOUNT]

I'm having 2 problems

1. I'm getting a "?" symbol when using Registration Tags such as [TOTAL_AMOUNT] and other amount related tags for PDF Tickets
2. QR Code does not generate on PDF Ticket.

Hello Anand

1. I guess we need to upload and configure a different font for your language. Not sure what's the language you are using? Please submit a support ticket sending us super admin account of your site so that I can check it

2. Depends on how you want to use qr code to checkin registant, you can use [QRCODE] or [TICKET_QRCODE] tag and qrcode should be generated. See eventbookingdoc.joomservices.com/advance...check-in-registrants for detailed instructions
