How Computers Store Text - ASCII, Unicode, UTF-8, UTF-16, and UTF-32

How do computers store text? In this video you will learn how we encode text into numbers, and decode those back into text. We'll talk about the ASCII and Unicode standards, as well as the UTF-8, UTF-16, and UTF-32 text encodings. The former standards represent characters and codepoints respectively to store text in binary. The UTF-8, UTF-16, and UTF-32 encodings are used to actually represent Unicode codepoints. The video gives concrete examples of how this works.

I had no idea how UTF-8 worked for years and in one minute I got a sense of how it worked. Great job with the video

It's a shame that a vide of such quality has so few views. Please keep making them, it's hard (I know), but at some point the views will grow up, hopefully exponentially.
