Somaliland

Only countries officially recognized by the U.N. are designated as ISO-3166-1 entities. Subdivisions are ISO-3166-2.

Somaliland is a self-appointed, unofficial country. It's no different than the disputed area, or the likewise self-declared Puntland region. As far as the U.N. is concerned, these don't exist. It's all Somalia.

Regional flags were never considered, which is why there are no individual state flags for the 50 U.S. states. Only the United States flag is represented.

Per the Unicode Consortium:

If the Emoji Subcommittee recommends the addition of a Catalonia flag emoji, then it looks like favoritism unless all the other subdivisions of Spain are added.

That's what you're asking. That a subdivision, that is not an official separate country, be given leeway no one else is allowed.

That and a 16 bit font can only hold up to 65,536 glyphs. Sounds like a lot until you consider if you counted every single municipality in the world (regions, cities, towns, etc.), there are roughly 4.3 million. You'd need 66 fonts just for flags to cover all of them.

FYI, you are not addressing Apple here. We are all other end users.

Emojis are the product of the Unicode Consortium and they have announced that they will no longer consider applications for new flag emojis. Their position is explained here:

Contact the platforms involved. Note that due to limited unit space and the large number of subnational flags worldwide, very few of them are actually implemented.
