Although I've run the gulp script to generate the fonts, it looks like there's something more needed in order for this to work in Atom -- have just tested and the icons just show up as coloured rectangles...

Sorry, because I'm looking at this because of the icons in VS Code, I didn't initially consider testing it in Atom! In VS Code, with a little tweaking of the theme JSON, the icons in the WOFF are showing up.

OK, well I managed to do some fresh testing with a new install of Atom this evening, and I guess something may have been screwed up with the old install (maybe doesn't help that I'm just replacing files in the package folder and restarting Atom). New fonts are working just fine now, though be aware that the file-sizes are now bigger than the original font-files.

Here's what they looked like before the update:

And here's what they look like now:

I don't know whether you have any more exhaustive testing you run through to check things out, but I just want to be clear that my testing here has been pretty limited.
