hterm: column misalignment with powerline fonts

Reported by linuxi...@gmail.com, Jun 13 2018 
UserAgent: Mozilla/5.0 (X11; CrOS x86_64 10452.99.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.203 Safari/537.36

Steps to reproduce the problem:
1. add Sourcecode Pro Powerline font to your terminal config
2. connect via secure shell, mosh, or any other hterm powered app to a remote server, run tmux, open a split, and open vim with a status line plugin in the left split.
3. observe the column misalignment

What is the expected behavior?
columns align properly, and width is preserved

What went wrong?
hterm isn't handling one of the fonts or escape sequences properly, i presume...

Did this work before? N/A 

Chrome version: 66.0.3359.203  Channel: n/a
OS Version: 10452.99.0

Here's a copy/paste from tmux of the status lines, but not sure if it'll be useful...

Related, probably, thanks to someone on the mailing list:

Actually...

This happens with vim-airline, even with a plain monospace font in hterm.

Just vanilla vim airline in a tmux split causes this behavior.

Comment 3 by linuxi...@gmail.com, Jun 13 2018 

I opened an upstream issue here: https://github.com/vim-airline/vim-airline/issues/1745

Comment 4 by linuxi...@gmail.com, Jun 13 2018 

Disabling unicode symbols fixes this, for now...

let g:airline_powerline_fonts = 0
let g:airline_symbols_ascii = 1

Status: Duplicate (was: Unconfirmed)
Summary: hterm: column misalignment with powerline fonts (was: hterm column misalignment with powerline fonts)
the powerline fonts you're using aren't actually monospace for some of the glyphs which breaks things
