Now you can set fonts/typeface directly in InDesign while creating PDF forms. This feature is now available in latest InDesign CC version. Please upgrade to the latest release.
This issue got fixed in InDesign CC 2019 (v 14.0) released in Oct 2018.
Please update to the latest version of InDesign (v 14.0.1), available via Creative Cloud Desktop app.
We thank you for your support.
