Please add SIL Open Font License (OFL) icons
I just found your font yesterday and it's great to have a source for beautiful, scalable versions of common OpenWeb symbols and icons.

While further researching icon fonts today, I found the SIL page, where they are defining the ["Human readable" version and visual representation](http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL#9ccf5052) of its license, with a nice set of CC-like icons. Those shown on the page are in PNG format, and shown in two sizes - making the need for a scalable version immediately clear.

It would be great if you could adapt and adopt these icons in your font!
Thank you.
