You should try to configure your terminal to use UTF-8. Symbols are universally used for quickly warning/informing in the real world and if done well, are very intuitive. Ignoring them in the digital world would be going against human UX (but no one ignores them, of course, even very old CLis already used them, but with the widespread use of UTF-8 and Emojis with that, it just became much easier and better).
