Add Powerline Extra Symbols

With my lightline config:

let g:lightline.separator = { 'left': "\ue0b8", 'right': "\ue0ba" }
let g:lightline.subseparator = { 'left': "\ue0b9", 'right': "\ue0b9" }

You can see some symbols don’t show as expected.

emm, isn’t that the purpose of g:fvim_loaded, which is already working?

btw it only works in ginit.vim, perhaps you’re trying it from init.vim?

update: added that to the readme. 😄

I shouldn’t call it an ‘option’. I just wonder if there’s a variable that shows I’m running Fvim. People may use multiple nvim front-ends, for example, when using Gonvim(It supports font ligatures) he can set font to Fira Code, and when using Fvim he can set other fonts he likes.
