I don't see that the SDKs provide ways of pulling the emojis out in a categorized list to choose from, it seems to all be about the conversion. If want a list of just emoticons, how would I do that with your SDK?
One more sorting question, how do sort within the category like at http://emoji.codes/ where all the smiley faces are together / people are together / etc. It has a very neat order. I've tried sorting by the unicode value but that wasn't it.
