Redhead emoji, along with other characters including bagels, cupcakes, superheroes, and llamas, technically launched on Tuesday when Unicode 11.0 went live.
But they aren't available for everyday use until the various platforms that host emoji update their systems to support the new characters.
On Wednesday, Android became the first platform to support the new emoji. In an email to Business Insider, a Google spokesperson confirmed that users of beta Android builds could start accessing and using the symbols immediately.
No other major platform has yet announced support, making Google the first. In the process, it is stealing a march on the likes of Twitter and Facebook, which have traditionally been quicker to update.
Google shared designs for a few of the emoji with Business Insider in the following image:
According to Google, the Unicode 11.0 emoji are available on any of the devices that support Android P Beta, which can be downloaded here.
They will be available to everyone else on Android when Android P's main update starts rolling out, which Google said is "later this year".
Twitter is partway through supporting the new emoji. It has published its designs for the new symbols but has yet to roll them out on its website. According to Emojipedia, this could happen as soon as the end of this week.
Business Insider has contacted other major emoji platforms, including Twitter, Facebook, Apple, and EmojiOne (which provides emoji for platforms like Slack and Dropbox), but none have responded with any concrete plans to support them.
