Powerline fonts display poorly

[Sparhawk]

I've installed vim-airline [1], which utilises powerline fonts. I installed the patched powerline font (for Deja Vu Sans Mono), but the triangles overhang over the lines slightly (see terminator.png). In comparison, gvim displays the powerline symbols cleanly, with no overhang (see gvim.png).

I can also see this problem in other programs that use this font, such as several zsh prompts. I'm happy to provide more information or troubleshoot if necessary.

Terminator 0.98
Arch Linux
KDE Plasma 5.5.4

I'm pretty sure that this is down to the terminal widget, and there is nothing the Terminator project itself can do about this. A few differential tests:
1) Does the same issue show in the GTK3 version of Terminator? (Much newer VTE widget)
2) Does the same issue show in GNOME Terminal? (Same VTE widget, different application)

If it shows in 1, but not 2 then it *is* a Terminator issue. I suspect though that 1 & 2 will be the same result, either:
 * both wrong - raise a but with VTE project, or
 * both right - fixed in newer VTE, and the "fix" for Terminator is to use the GTK3 version of Terminator.

(The older VTE used in GTK2 is no longer updated/fixed/loved, etc.)

Raise a **bug**. Probably best not to go around raising but's :-D

This one's being tracked at https://bugzilla.gnome.org/show_bug.cgi?id=682635.
Could you please copy-paste the given status line, so that we can tell what Unicode code points they are?

@Stephen Yes, you are correct, it does show up in both, so the newer VTE still doesn't work (as Egmont suggests).

@Egmont Thank you, I've posted upstream.

[Sparhawk (sparhawkthesecond)]

@Stephen I mean it shows up *incorrectly* in both. As a but. :p

Marking as invalid/not-responsible, as the issue is in libvte, and there's an open bug.
