It looks like this

It's quite modular so you can easily add/remove/rearrange segments, see lines 85-89

You need to use PowerLine enabled font therefore ConEmu is highly recommended because of color schemes and font handling.

Same here, not really sure what the issue is. @dl1ely did you ever figure it out?

When downloading the ZIP the file comes encoded as "UTF-8 without BOM" which Windows does not seem to like very much.
Open the file in Notepad++ (or another unicode enabled editor) and convert it to "UTF-8". This does solve the issue for me.
