black and white fonts

[sginoza]

Describe the issue

Is it possible to set a preference for black-and-white fonts?

Section 3.2.1.1 of draft-ietf-jsonpath-base included the following:
U+1F914 ("🤔", THINKING FACE)

This was changed to the following to avoid color:
U+1F3BC (“🎼”, MUSICAL SCORE)

pdffonts showed it was using the following font:
NWKMBL+Noto-Color-Emoji

Carsten noted that we "could use 'Noto Emoji' instead of 'Noto Color Emoji'; this is properly black-and-white."

Note: this is not currently delaying publication of any documents. draft-ietf-jsonpath-base has been published as RFC 9535, which uses U+1F041 ("🁁", DOMINO TILE HORIZONTAL-02-02).

Looks like prioritizing Noto Emoji over Noto Color Emoji will hit a WeasyPrint issue: Kozea/WeasyPrint#1848

A workaround for this is:
Removing Noto Color Emoji from the system and installing Noto Emoji font from https://fonts.google.com/noto/specimen/Noto+Emoji
Note that the Noto Emoji font provided by https://noto-website-2.storage.googleapis.com/pkgs/Noto-unhinted.zip is old, and doesn't cover a lot of codepoints.
