Airline line indicator symbol is empty / not found

[alpertuna]

environment

• vim: 7.4
• OS: Debian Jessie
• terminal: XTerm
• $TERM variable: screen-256color-italic
• color configuration (:set t_Co?): 256
• font: DejaVu Sans Mono for Powerline Nerd Font Complete Mono.ttf

Hello,
A square character is appeared near line indicator, and I found g:airline_symbols.maxlinenr keeps that char and I am able to correct it from .vimrc, but I wonder why its default value is look like square.
That character is '☰'

Can you try https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/DejaVuSansMono/Regular/complete/DejaVu%20Sans%20Mono%20for%20Powerline%20Nerd%20Font%20Complete.ttf instead?

I believe this is related to #92 (comment)

@ryanoasis
I tried it but still the same. I looked #92, there is no problem like that, I can see that icons with my font.
The problem is about just this char I saw.
I inspected the character and;

Its hex code is 2630
And that character is empty in font map

[ryanoasis]

Thanks for the details. Looks like the characters in range 2630 through 2637 (trigrams) are missing even in the unpatched Nerd Fonts powerline source of DejaVu Sans

So it looks like these were missing from the source font Nerd Fonts patches. This is not a bug with Nerd Fonts itself however we could make an improvement to patch in these missing glyphs if detected 😄

[alpertuna]

+1 😊

[ryanoasis]

These are missing for some reason (along with many other glyphs that are in the Deja Vu Sans condensed).

I have not attempted to fix all of them (that would take way too long) but I did copy these trigrams from the appropriate condensed version to the mono versions for now.

I also updated Deja Vu fonts from version 2.33 to 2.37 (see deja vu changelog)

[alpertuna]

Thanks 👍 I already use some alternative ways for missing glyps, so time is not problem 😊

[ryanoasis]

What are the alternative ways you are using if you don't mind me asking? Fontconfig?

[alpertuna]

I use Xresources to set font, and I specified more than one font as fonts chain so that if a char is not defined, it searches next font family for that char.

Now really fixed for all fonts via #1125
