The debdiff for this upload includes changes e.g. to fonts-noto-color-
emoji-0~20180810/emoji_aliases.txt that change existing behavior:
-1f46a;1f468_200d_1f469_200d_1f466 # FAMILY -> family: man, woman, boy
The Makefile has started to pass a -S "small metrics" flag to
emoji_builder.py that was not previously in use; and previously the
script defaulted to "big metrics".
How do we ascertain that these changes do not regress consumers of these
fonts that may be relying on the existing behavior? I don't think the
regression potential has been adequately addressed with the current SRU
template.

Title:
Update fonts-noto-color-emoji to 20180810 release for Unicode 11
Status in fonts-noto-color-emoji package in Ubuntu:
Fix Released
Status in fonts-noto-color-emoji source package in Bionic:
Incomplete
Bug description:
Impact
======
Google has released the latest version of their color emoji font that is
shipped with Android 9 "Pie".
The new release is a major upgrade, including support for the new Unicode 11
standard. Some existing emoji were tweaked.
We need this update in Ubuntu 18.04 LTS so that the new emoji work.
https://blog.emojipedia.org/whats-new-in-unicode-11-0/
https://blog.emojipedia.org/inclusive-emojis-coming-back-to-android/
https://emojipedia.org/emoji-11.0/
Note that several of the new combined emoji (like red-haired man 👨🦰 )
will need an update elsewhere (pango?) to display as combined.
Test Case
=========
1. After installing the update, visit
https://unicode.org/emoji/charts/full-emoji-list.html
The browser column should match the Google column
2. You can also use the Characters app shipped by default to verify
that the emoji seem to work ok.
Regression Potential
====================
Except for being rebuilt from source in Ubuntu, this is basically the same
emoji font Google ships in the latest Android.
We can easily verify that the update is successful by completing the 2
test cases above.
Other Info
==========
Google does a major update of this font once per year corresponding with the
annual release of the new Unicode standard and Android.
Proposed pango update:
https://gitlab.gnome.org/GNOME/pango/merge_requests/15
gtk3 could then probably use an update to get the new emoji in its
emoji chooser.
Most other GNOME distros (including Debian Testing and Fedora 28) also
use this font as their default color emoji font.
