As a side note: you not technically need a domain or a let’s encrypt certificate to enable https. As a test you can create your own certificate, and use that for https (snake-oil certificate).

This is not appropriate for longer-term usage. If you want to run websites on the Internet long-term, you should buy a domain and get a lets-encrypt certificate.

There are also the colored circles 🔴,⭕ and 🟢. The worst part for me is that while the emojis are technically one char in code, they are usually displayed with a 2-char-width.
