How to put emojis in my Twitter bio?

Coloured emojis, like this:

where do you get them from and how do you put them on your Twitter bio?
( I know they're from some phone app, but I downloaded go SMS pro because I was told that was the one but i can't get them onto twitter. Can you only do this if you have an iphone or something?) x

If you have an iPhone you can download the emoji app and once you download it it think you have to enter the app and follow what it tells you to do (sorry it's been awhile since I've used it) and once you get into the app you can either copy and paste the emojis or you can go into your phones settings then to general then to keyboard and then click keyboards and then click add new and you should find one that says "emoji" once you click on that you should be able to close the settings and then next to your space bar on the left you'll have a little globe icon and if you click that your regular keyboard will disappear and you'll have an emoji one. It used to be that emojis could only be used on iPhones but now I think android phones can have them too. Another option is to google something like text symbols and copy and paste from there.
