Legacy PUA emojis

[Crissov]

I found some code in the repository that handles legacy Google PUA codes for the ten original emoji flags and for keycaps. To view some old data that I either do not want to or cannot convert to proper Unicode codepoints, it would be nice to build a (non-default) version of the font that supported more and other PUA codes. Every Japanese carrier had their own (and Apple shared a set with Softbank).

Example: Thumbs Up

Unicode	Apple iOS / Softbank / Yahoo / Disney / Vodafone / J‑Phone	KDDI au EZweb (a)	KDDI au EZweb (b)	NTT Docomo i‑mode / Willcom / E‑Mobile	Google Gmail …
U+1F44D 👍	U+E25A 	U+E4F9 	U+EFD2 	U+E727 	U+FEB97 󾮗

I could provide a file with these mappings, but I'm not sure how and where to include it in the code, so cannot really write a pull request myself – unless someone could provide some helpful pointers.

Sorry, forgot about this. If you want to make modifications for your own use, you can try adding the mappings to emoji_aliases.txt. What I don't remember off the top of my head is whether the build will generate empty default glyphs for the PUA codepoints. I haven't checked.

@Crissov did you try editing emoji_aliases.txt?

[Crissov]

Like so? https://github.com/Crissov/noto-emoji/blob/legacy-pua/emoji_aliases.txt

[dougfelt]

Yeah, that's the idea. Have you tried building a font with this and testing it?

Since you don't sort by the alias codepoint I can't tell if any of them appear more than once. I think the last one mentioned would win in that case. That's the thing with PUA, anyone can use any of them for anything.

[Crissov]

I have not build a font yet.

Most codepoints between U+E501 and U+E537 appear twice, should probably remove the rare KDDIa variants.

Closing this. I don't think it's something we want to do.
