PDF Library : font on Android

I use your Library which runs very fine on Windows, OSX, IOS and Android.

It's supplied as Cross Platform on these plateforms.

But it's not possible to embed a font on Android. The Library only uses the installed fonts on the device, despite your answer here :

I can't ask my clients to root their device to be able to install fonts on Android.

So : I would like the Library to run on Android as it runs on Windows and others, and to embed fonts that are supplied with the application.
