There should be one font available for unicode and emoji so they look the same across platform.

The suggested fonts were Noto Emoji and Not Color Emoji.
They should be ideally be used in addition to Roboto.

It was proposed to merge the 3 fonts in a font editor.

This issue was a proved in today's meeting

Why not just use Noto Sans for regular text instead of Roboto?

Can't use Noto Color Emoji - only works on Linux and Android:

This font format is supported on Android and Linux, but doesn’t work on macOS or Windows.

OK, support for the color font format Noto Color Emoji uses might have improved since that page was written, but is still not universal:

NotoColorEmoji uses the CBDT/CBLC color font format, which is supported by Android and Chrome/Chromium OS. Windows supports it starting with Windows 10 Anniversary Update in Chrome and Edge. On macOS, only Chrome supports it, while on Linux it will support it with some fontconfig tweaking, see issue #36. Currently we do not build other color font formats.

I don't see a reason not to use Noto Sans (or Roboto) and Noto Emoji as our standard font.

I misunderstood the font fallback QA I found on stackoverflow during the meeting. Fallback does work at the glyph level. So there should be no need to make a custom font containing all glyphs we want. We can even limit the glyphs available in a google font if we want to use it for some of its glyphs but not others:

Does the combination of Material Icons and VTT-Symbols satisfy this issue?

[RaphaelAlvez]

It does but it doesn't deal with this problem directly but it solves the problem this issue was trying to solve.
I wanted emojis for the PL.
