Adding subdivision flags, USA

[KeijttaWolf]

Copying this pull request over from the previous project, twitter/twemoji#411. I lost access to my old account "Keijtta" so I'm publishing this with a new account. This pull request does have some changes: - It does not include the outlying area, but can be added if that is requested. - Includes the new flags for Minnesota and Utah that were adopted in 2024. - Added few changes to Idaho, Nebraska, New Hampshire, Pennsylvania, South Dakota to make them closer to their real life flags.

What are subdivision flags?

With Emoji version 5.0 (Unicode 10.0), subdivision flags was added to the standard. Any subdivision specified in ISO 3166-2 are valid for an emoji representation, and can be represented by a flag if there is one. For example, US-TX stands for Texas, and US-CA stands for California.

As of now, the only subdivision flags supported by Twemoji are England (⚑gbeng✦), Scotland (⚑gbsct✦), Wales (⚑gbwls✦) – WhatsApp has also added supported support for Texas (⚑ustx✦)

Please see this comment on a similar issue for Twemoji's general stance on subdivision flags right now. We'll keep this PR in our back pocket in case, in the future, we're able to expand support for non-RGI emoji (or even just all the subdivision flags).

@jdecked I appreciate the reply and the comment does go over many valid reasons.

I do appreciate that you'll keep the PR around in case there's interested in adding these.

I started with USA first to test the waters. I could see these subdivisions being the most sought after by uses on X and Discord, since those platforms use these emojis and those platforms have many users from USA. But then I would move over to other regions such as Canada, Germany, Japan.

I've done rough estimates on how many flags there would be, and it's somewhere above 1500, which is still a lot, but there's a lot of regions without subdivision flags such as China.
