Have you encountered an issue that the Chinese characters in invoice are garbled? Some of the people reported to us and they need to buy a module for this problem. Actually you just need to change a line of code and it will be fixed. Since we usually use Linux server to host the Prestashop. In server, open a terminal and type the following command to make some change in a program file.
sudo nano /applicationfolder/classes/pdf/pdfgenerator.php
and in line 30 replace all “helvetica” into “kozminproregular”
