Ref T12139, installs 'Segoe UI Emoji' as a standard font call for color emoji on Windows devices.
(On windows/chrome) this seems to have changed the overall font for many Phabricator elements to a slightly different font that in my mind is just a little less readable. Apparently re-ordering 'Segoe UI Web Regular', 'Segoe UI Symbol' in front of the regular Segoe UI changes how the font looks.
Not sure if this was an intentional side effect or not, not a big deal either way. I can grab screenshots of before/after.
What it looked like before
It's a subtle change...
Also (not my capture) but even now this is roughly how emoji looks for me on Windows 7. Maybe it looks better under windows 10, I don't have Segoe UI Emoji as a font though... so I fall back to the less pretty glyphs. Not really a big deal, just a note. I'm happy to report back how it looks tonight from a Win10 system.
