So, some tools that might help with icon fonts:
-
Build fonts from existing glyphs:
IcoMoon — meta-resource, using font-awesome & other fonts, either publicly available or purchasable
flaticon -
Build fonts from your own images online, but needs editing special template:
IconVault -
Something in between:
Fontastic -
Build your own font on your local machine: sketch + fontcustom + middleman to create your own font
Inkscape (a bit outdated)
Grunt
There’re also a lot of known bundles of vector icons that can be utilized to create custom fonts -
There’re also specific fonts if you’re going to dig long enough, like mapglyphs.
