In the Noto set of fonts, recently mentioned in news due to reaching a milestone of 800 languages and 100 scripts, and available from https://www.google.com/get/noto/
the NotoColorEmoji font appears to be broken. I installed all Noto fonts
on my Windows 10 (simply dragging and dropping the entire set into the
Fonts folder under Control Panel), but NotoColorEmoji was reported as
broken, not installed. I checked with DTL OTMaster, which also reports
it as broken.
Am I missing something? Does NotoColorEmoji use some font technology
features that are not handled by vanilla Windows 10?
The original TTF font format was monochrome. It did not support coloured symbols. The OTF font format extended TTF but was still monochrome.
To support coloured emoji, the TTF/OTF font format has been extended in
four different and incompatible ways.
Google: CBDT/CBLC
Apple: sbix
Microsoft: COLR/CPAL
Adobe/Mozilla: SVG in OT
The NotoColorEmoji font which you have uses CBDT/CBLC.
Microsoft Windows 10, on the other hand, supports COLR/CPAL.
If you go to
https://www.google.com/get/noto/help/emoji/
it says this about NotoColorEmoji: "This font format is supported
on Android and Linux, but doesn't work on macOS or Windows."
Here is a article about the different colour extensions to TTF/OTF.
