Hi everyone, I got the solutions about BDT (৳) showing problem in invoice, hopefully it will work for any others unsupported currencies symbol like Rupi/etc. You need to change the PDF invoice fonts basically from default to "freeserif". This font working for me, you may can retry with some others if you want. Location is: Blesta Admin---> Settings--->Company--->Billing/Payment--->Invoice Customization---> Font Family (freeserif), that's all.
