Hello @priyankajagtap
Thanks for your reply, and providing the patches.
I tried the patch you provided, but it didn’t fix the garbled characters in the PDF.
You didn’t mention it, but I put the “wcdn-front-function” you provided in “plugins/woocommerce-delivery-notes/includes/front”.
You also mentioned the font storage folders as “/font/” and “/fonts/”, so I tried both, but it didn’t work.
You already know, the PDF will display normally if I open it in another software (such as Google Docs).
