IRC doesn't actually specify an encoding for messages, only limiting each message to 512 bytes IIRC. This could and did cause encoding issues when dealing with non-english language text.
I've seen people use "constructed" instead of "artificial", and I think it does make sense because it relates to the human action and intention behind the changes we make to the environment. I'm not too sure what would be the alternative to "natural" though.
the only downside for me is that there aren't many mature UI libs for it yet. I was evaluating it for a Tauri-based project but I went with React instead because of this.
