When looking at the Desktop soft phone app, I notice that only a small subset of SMS emoji characters are available to choose from. I've also noticed that both incoming as well as outgoing SMS which includes other emojis not listed in that menu (such as those generated by the iOS emoji keyboard) may or may not always come across thru RingCentral.
Is there a list of supported emoji characters and the appropriate way to encode them for use via the REST API?
