Unable to display special characters in patch font about lightline.vim

[itchyny]

How about the following config?

      \ 'separator': { 'left': "\ue0b0", 'right': "\ue0b2" },
      \ 'subseparator': { 'left': "\ue0b1", 'right': "\ue0b3" }

Note: use the double quotations.

Can you try powerline (https://github.com/Lokaltog/powerline) and check whether it works?

[paullemmens]

Unfortunately, I did not understand well how to install Powerline. In any case after copying around a few files, gvim complained that it was not compiled with (the proper) python support. I use a precompiled windows binary of version 7.4 that was released a month ago.

Would it help if I sent my full .vimrc so you can check for conflicting settings or something?

[itchyny]

What about vim-airline (https://github.com/bling/vim-airline)?
It is not based on python so you can install it.
I want you to judge if this issue is due to a bug of this plugin or a bug of GVim for Windows.
Powerline has lots of users and is a matured product so it's a good plugin to compare.
vim-airline is a new plugin so both plugins (vim-airline and lightline.vim) can hold the same issue.

[paullemmens]

I understand your preference for powerline! Unfortanately time nor skill permit me to get python up and running, so I installed vim-airline. Still no joy; the powerline fonts are working in the text (see my screenshot). I made sure to remove the lightline.vim plugin file and then the screenshot became the following.

To summarize the result, there's two cases.

• In GVim for Windows, vim-airline and lightline.vim hold the same issue around the patched-font (for Powerline).
• GVim for Windows holds a bug around statusline.

[itchyny]

Ah, here's a quick test.
Try the test without lightline.vim and vim-airline.
Firstly, you execute the following command.

set statusline=hello

The statusline will say hello.
Then, try the following command.

set statusline=

If the statusline does not show the triangles, it is a bug of GVim for Windows.

[paullemmens]

1. I cleaned out my entire vimfiles folder and fired up a clean gvim.
2. set encoding=utf-8
3. set guifont=Inconsolata\ for\ powerline:h13
4. set statusline=hello

WORKED

5. set statusline=> (you know the big one from the patched font)

WORKED (see below)

[paullemmens]

And a quick addition, I just copied back my vimfiles folder but now commented out everything except the three relevant things (encoding, guifont, and laststatus) as well as airline airline settings. Still no joy, so it appears not something in the vimrc.

[itchyny]

Another test.
Disable lightline and airline.
Then add the following config in vimrc.

function! MyStatusline()
  return ""
endfunction
set statusline=%!MyStatusline()

Restart GVim.

W00h00 ... your last suggestion with "\uXXXX" did the trick.

Thanks for bearing with me and all the detailed suggestions!

[itchyny]

Nice. I'll add to the document.

[her]

hey @itchyny

I really love lightline so far thanks for all the hard work. your suggestions about ue0bx fixed my glyph issues

I'm just wondering though: how did you know this would fix the glyph issue? is there a place where I can find these codes associated with these glyphs?

thanks again 😄
