Title: new SEGMENT_SEPARATOR which works with most standard fonts

the previuous separator was not working for me (and some friends of mine) even with the powerline patched fonts. I copied the arrow from https://gist.github.com/agnoster/3712874 and pasted it into my configuration. Now it works with nearly every font.
