Hebrew language docx to pdf conversion is not working properly

Hi All,

I have a requirement for converting hebrew language DOCX Document to PDF Document.I have tried to convert using "PDF from Single DOCX (with Fonts)" Smart Service from dynamic document generator(https://community.appian.com/b/appmarket/posts/dynamic-document-generator).
But Hebrew Language content is replaced with ### symbol in created PDF Document using this smart service.
So I created constant, added two hebrew ttf document ("NotoSansHebrew-VariableFont_wdth,wght.ttf","NotoSerifHebrew-VariableFont_wdth,wght.ttf") and added as Font Documents in that Smart Service.
But still I got the same PDF document with replaced ### symbol.

Could you please suggest, what kind of font document we need to upload for hebrew language to get original Hebrew Language PDF Document? 

Also I have used "HTML Doc from Template"  Appian smart service to create a HTML document with Hebrew content and using the generated HTML document I tried using the "HTML to PDF" Smart Service  from "HTML To PDF Conversion" custom plugin but still we are facing the same issue.
