Button icons offline

[jifcon]

Hello!

I'm trying to develop an app (voila) that has some buttons and I included icons from FontAwesome. My question: Is it possible to include these icons if the application is going to be offline? I tried and when is offline, it shows squares instead of icons.

Thanks++!

There is this very similar issue on Thebe, where icons are missing because Thebe simply does not include Font-awesome: jupyter-book/thebe#185

I wonder if the best approach should not be to have ipywidgets ship font-awesome instead of assuming the Jupyter client provides it?

I believe the best approach is to not use icon fonts at all. Instead use SVGs. This is what Jupyterlab decided to do years ago: jupyterlab/jupyterlab#30

Icon fonts are a bad idea. They interfere with user preferences about what fonts they want to see things in. Fonts are for text; UI icons are not text and should not use fonts; they are images and should use images.
