Presentation Style

This is an early request for Twemoji, Twitter has released and implemented the latest Emoji available first on iOS 9.2 and OS X 10.11.1, there are huge improvements, all emojis are included but there are some possible bad implementations.

The Copyright sign, the Registered sign and the Trade-Mark sign have been not included in the V2, Unicode standards stay that they should be displayed as emojis only if they have the U+FE0F VARIATION SELECTOR-16 (VS16), so, instead of being only a9, ae, 2122 they should be a9-fe0f, ae-fe0f, 2122-fe0f to be displayed as emojis, but there is no PNG URL for those with or without the modifier, they are only available on V1

As they are emojis, they should exist in the following urls: https://abs.twimg.com/emoji/v2/72x72/a9-fe0f.png https://abs.twimg.com/emoji/v2/72x72/ae-fe0f.png https://abs.twimg.com/emoji/v2/72x72/2122-fe0f.png

They are only available in V1 in the following urls: https://abs.twimg.com/emoji/v1/72x72/a9.png https://abs.twimg.com/emoji/v1/72x72/ae.png https://abs.twimg.com/emoji/v1/72x72/2122.png

I forgot to add two screenshots showing how Apple implemented both versions, with and without the emoji modifier:

IIRC for backward compability this has been a well known exception in the normalization logic.
