Description
They only render at half width. They render fine in the terminal:
See this issue here: It seems to be an issue with Macvim. (Can reproduce on latest release).
(I currently summarized the Mac OS behavior at the end of the thread): https://github.com/ryanoasis/vim-devicons/issues/133
Setting CoreText Renderer=off fixes the problem and tanks perf/quality.
Setting ambiwidth=doub.e does seem to fix some of the icon drawing, and has some other remaining issues such as the following rendering of airline (latest MacVim, font=PragmataPro).
Notice the gap next to the arrow. That only shows up with ambiwidth=double.
