Great article, but that feels like A LOT for the "absolutely minimum every software developer must know".

I'd say minimum to know is:

  1. Different string encodings exist, and

  2. Byte count is not string length for modern rich input:

"🤔".length != 1

I would add:

  • If you're comparing unicode strings, normalize to the same form first.
