you could try changing the font used in the PDF invoice by changing the setting in setup -> general settings -> invoices -> PDF Font Family

if you're using the default "Six" template, then the font used should change with this setting; if you're using an older template (or one from a previous version), then the font used to be defined in the template itself and this change would make no difference.

have you tried switching your site to use the "Six" template? if you do that, and make an order - if you don't get the error message, then the issue is with your custom invoicepdf template; if you still get the same error, then there might be a missing/corrupt font.

also, it's worth noting that you haven't added any domain pricing yet - until you do, customers won't be able to order your hosting products that require a domain with a domain registration, they'd need to use an existing domain.
