Menlo Regular, patched to support glyphs from FontAwesome, Powerline, Octicons and more.

As I found, everyone else uses Meslo - customized version of Menlo with 'fixed' verical line spacing and changes baseline alignment of asterisk.

As for me, I like original Menlo spacings and aligns, so I decided to stick with original Menlo, but to patch it to add support for glyphs and icons from other modern and popular libs/collections.

• Font Awesome (+ andrelzgava/font-awesome-extension)
• Material Design Icons
• Octicons
• Powerline (inc. ryanoasis/powerline-extra-symbols)
• Pomicon
• Weather Icons
• IEC Power Symbols
• Font Linux

• *-Full - version with all icons and glyphs.
• *-Normal - version with added powerline(with ext), font awesome(with ext) and octicons.
• *-FullV2 - same version as *-Full, but with aligned powerline glyphs.
• *-NormalV2 - same version as *-Normal, but with aligned powerline glyphs.
• *-Mono - same version, but in monospace variant (with single-width glyphs).

I guess you can't. These glyphs placed in Private Use Area (starting from U+E000) and Symbols Viewer cannot show them. On OS X, use Font Book.app.

Also, you can use helper scripts from here to test glyphs in terminal.
