Hello,
I'm using xterm and xterm's font-face setting to use patched font so not gvim but it doesnt matter, anyway.
This is DejaVu Sans Mono font and there is a problem.

As you see at right side there is a little space after airline arrow icon, at left side there is not problem like that. Furthermore, font size is 10 now and when I increase it, space width also increases.
My old DejaVu font which patched only for airline, there was no problem like this.
Also this problems appears on many of that fonts, I didnt try all of them but.
This is unconfortable. If we can fix this, I will appreciate it.
@alpertuna Hey thanks for the report. :+1:
I have seen and/or had this problem before as well.
I am not sure how much can be done to eliminate this 100% but I will look into it nonetheless when I get some time
@alpertuna Can you try downloading again with latest release?
:+1: Perfect, it seems problem solved.

By the way this is DejaVu... mono one. And terminal is xterm, not gvim.
When I try non-mono font, left and right letter spacing is very huge in xterm but for gvim no problem again.
In the past also had this issue. However mono one does the job now so not problem for me, thanks :)
Yeah mono one looks fairly good, here is my vim in xterm with DejaVu:

And non glyph mono of DejaVu:

I think problem is solved :relaxed:
