I think the real problem isn't that some clients support emojis and some don't, it's that Signal is a security product and lowest common denominator in the installed base can mean broken security. I can see why Moxie makes this tradeoff, but I am also pleased by the way the encryption system is making its way into other platforms. Hopefully, this will over time result in some kind of useful ecosystem, but you might only want to trust the part of it that is more strictly controlled for "serious business".

There is no interoperability between systems that use ideas from Signal Protocol and it is unlikely that there will ever be. There is no published standard. The best you can do is transiterate existing source code. It is a very complicated protocol with lots of state. It requires a server infrastructure to work. To be interoperable clients need access to information on the same server. The protocol is simply not designed for interoperability...
