Hello.
I’ve been using Vim and the vim-airline plugin for a long time, but I haven’t seen something weird like this before (see the attached photo). I see odd charaters in the status line, frequently when I switch between open windows (by Ctrl + Tab) or when I save a file.
Any hints? or an alternative status line plug like airline (I tried lightline and vim-statusline, but airline is top)
For the nice looking powerline symbols to appear, you will need to install a patched font. Instructions can be found in the official powerline documentation. Prepatched fonts can be found in the powerline-fonts repository.
Finally, you can add the convenience variable let g:airline_powerline_fonts = 1 to your vimrc which will automatically populate the g:airline_symbols dictionary with the powerline symbols.
You need powerline-fonts.
