The gaia-icons font currently uses ligatures to place icons, see here

The ligature character sequence is derived from the original filename
of the SVG source file in `images/`.
Is this what you were referring to?
OK, so if you're using ligatures to access the icon glyphs, can you
modify the script that generates this font so that it does NOT assign
PUA codepoints to the glyphs at all? It should be possible to leave them
unencoded (i.e. with no entry in the font's cmap), so that the only way
they can be accessed is via the ligature sequence.
I see you're embedding the generated font directly in a CSS file as a
data-URL. How's the performance of this approach? It won't be quite as
efficient as installing the font in the base OS, because each app that
uses it will be instantiating its own separate copy, so there must be a
memory and perf cost. But maybe it's good enough?

How difficult would it be to have your grunt script add a dlig table
to your font?

We are using icon-fonts in some of the new web-component based
building-blocks examples. I have created a gaia-icons repo so that our
components can explicitly depend on these icons. Inside this repo we
have all the source SVGs inside `images/`. A grunt task called
grunt-webfont converts all these SVGs into a single icon-font. To add
new icons, you simple have to drop new SVGs into the `images/` directory.
