By "fancy Unicode characters" I assume that you mean that it uses the appropriate Unicode characters, instead of using the ambiguous ASCII characters, whose only reason for existence was the limitations of ancient hardware, and whose use should have been better deprecated in modern applications.
Probably. These characters do not render properly in my setup (Emacs, SLIME REPL). Gemini and Claude use ASCII.
Wow, that's awful. I wonder why they do that.
Sounds like you should improve your setup ;)
there's a lot of things I could be doing with my time. posting on random internet forums ranks higher than figuring out ascii vs utf in one more system.
Retrofuturism, using AI and not having the editor set up to render Unicode characters.
By fancy unicode characters he probably means HN won't allow them in comments.
