The fonts in the in file are not loading correctly in the flipbook. In every other PDF viewer (desktop software) I have tried such as Acrobat, native OSx preview, chrome browser, Word etc the document fonts are displayed correctly. Its not all fonts either.

This file is made monthly and last 2 months has failed. The producer advises no change BUT when I look at the file I do see this information change.
When I viewed the source.
Here is the current PDF (linked above)
Creator CCI Europe (PDFGenerator Release CUEPrint3.26.0.2z)
CreationDate D:20230724181512+08'00'
Producer Artifex Ghostscript 10.01.1
ModDate D:20230724181512+08'00'
Here is an older one
Creator CCI Europe (PDFGenerator Release CUEPrint3.26.0.2f)
CreationDate D:20230217170218+08'00'
Producer Artifex Ghostscript 9.55.0
ModDate D:20230217170218+08'00'
So the ghost script version has changed?
Since I need a working 'book' display, and I have no options to change the production process on the PDF, I guess lacking a response here I need to find an alternative.
probably you need to set cmaps folder url: https://3dflipbook.net/documentation#using-in-frameworks
