đŸŗī¸â€đŸŒˆ Rainbow Flag Emoji Details Published

A document describing how vendors can implement a Rainbow Flag Emoji has today been published.

This document, written by Mark Davis and the Unicode Emoji Subcommittee[1], details a sequence that vendors can use to support a pride flag emoji on their systems without waiting until 2017 for Unicode 10.0.

This document states that consideration of this flag was "met with strong vendor support" when assessing new options for emoji and gender. It goes on to state:

The Emoji subcommittee decided that although the rainbow flag is related to gender, it would be cleaner if it were described in a separate, smaller, document.

The rainbow flag features in the Emojipedia Top 30 requests, and has been requested of Unicode as far back as June 2015.

How

The proposed method to implement this flag is as an Emoji ZWJ Sequence joining the đŸŗ Waving White Flag and 🌈 Rainbow emojis together.

If you just said "a what?", this explains:

The actual sequence of Unicode characters is outlined as follows:

The implementation of this emoji as a ZWJ Sequence does not affect how it is seen by end users, with supported systems to show this alongside any other emoji.

Approval

As with all Emoji ZWJ Sequences, vendors are free to implement this right away if they wish.

When asked whether these require any form of approval by the Unicode Technical Committee, Mark Davis, President of the Unicode Consortium said:

"ZWJ sequences are not subject to approval by the UTC, because they do not add new characters".

Basically: no approval needed from here. Vendors, go forth!

Why Document It

If Emoji ZWJ Sequences don't require Unicode approval, why document this emoji at all?

The primarily benefit of documenting this sequence is that it ensures consistency of implementation.

If vendors went it alone and added the rainbow flag emoji prior to this document, they may have individually chosen combinations such as:

  • 🌈đŸŗ
  • đŸŗ🌈
  • 🌈🏴
  • 🏴🌈

Any of these would be just as valid, but of no use in ensuring cross-platform functionality.

As it stands today, Emoji ZWJ Sequences could be made by vendors for all kinds of combinations, including flags. For instance:

  • ☠ī¸đŸ´ Pirate Flag
  • 🔩⚙ī¸đŸŗ Nail and Gear Flag

Technically nothing stops vendors implementing these flags today.

Having new Emoji ZWJ Sequences documented by Unicode is a way to ensure that if other vendors intended to introduce the same sequences, they would use the same emojis, in the same order.

Basically, documentation = better cross-platform compatibility.

When

Users could see this rainbow / pride flag emoji included by supporting vendors by the end of 2016.

Note: despite being a flag, this has no relation to how other flags such as England, Scotland and Wales would be implemented, if approved.
