WebHostingHub Glyphs is a most comprehensive set of glyph icons available as font. The goal is to be fully compatible with Bootstrap and other frameworks and CMSs. It will be constantly updated so if you have ideas for new icons, do let us know.
Not sure if this is a whhglyphs issue of an SVG parsing issue in some apps, but in apps like fontastic.me, importing the SVG file results in the icons having a high baseline and getting clipped. However, in apps like IcoMoon, this isn't an issue. This is not an issue with the TTF on the desktop or an issue I've experienced with other icon fonts.
