Problem with fonts not displaying correctly in Acrobat
Hello!
Hoping for some advice on a font display issue we are facing.
The pdf files we're using are supplied by the customer with all fonts embedded subset and everything displays fine. When the pdf file has been run through the developers software the font is coming out as below. All fonts are still embedded subset but as you can see the text is not displaying correctly.

I have tried turing off use local fonts and some other suggestions I've found on other similar posts but none of these seem to work. The software the developers are using have produced plenty of files for this customer without this issue occuring. Is there anything I can look for that might highlight what is causing this issue?
many thanks
Laura
