Unable to load all icons 
I tried to load those icon fonts without the bundle:
- ionicons
- font awesome

On OSX El capitan i download each icon set and:
- Installed the TTF file
- On sketch i installed the font selecting the SVG file.

Now i'm able to search icons but a lot of them are missing.
Looking at the Font Book app of OSX the icons are present.

An example is the "gear" icon from ionicons.
