Does this skin need Font Awesome?

[dandv]

This skin doesn't bundle Font Awesome, and the example doesn't link to it. But, the .less file tries to load Font Awesome on line 3348.

Is Font Awesome still necessary for some elements of the Webix UI when using the Material Design skin?

Table headings need an arrow character that comes with Font Awesome:

All skins seem to need that character. For example, Flat:

Font Awesome is a pretty large dependency. Would it be possible to replace that special up/down character with a Unicode character that comes with a standard font?

Skin uses FontAwesome for icons similar to the default skin.
I will add the missed files as part of #2
