I am using the Graph API convert content API (v1) to convert my SharePoint Online hosted files (docx) into PDF files.
The conversion has been working fine to date, however, I have now added custom fonts (proprietary) into the word doc - then I save the word doc with the font embedded.
I can open the docx file in SharePoint online and see the custom font - but when I convert the docx file to PDF using the Convert content API (https://docs.microsoft.com/en-us/graph/api/driveitem-get-content-format?view=graph-rest-1.0&tabs=http) the font is dropped from the PDF and it reverts back to Calibri?
Is this a known limitation, are ther any work arounds that are in place for me to use custom fonts? This is critical for our clients brand to proceed.
