Failed to deencode argv

[redwill17]

I installed wtype in order to use it alongside https://github.com/marty-oehme/bemoji, which supposedly can send the emoji output to wtype

But it doesn't do anything, and typing wtype \360\237\230\255 or any number code for any emoji will throw Failed to deencode input argv. Is this intended behavior? Do I have a way to type emojis? It shows the same error if I run bemoji in a terminal
