This doesn't really cover, for example, Chinese character use case. That was also not a great situation overall. If you encode something as one of them and decode as another, it will come out as garbage. There's an example where there's characters in two different character encodings for the same language, so both for Cyrillic languages. Then there's other encodings for other languages, like there's the Cyrillic variant in that standard. That is for Western languages, you can write Spanish, French with it, languages like that, German too.

For example, there's Latin-1, which stands for ISO 8859-1, but rolls over the tongue a bit more nicely. We're just going to create a lot of character encodings that covers some specific languages. ASCII is 7-bit, which means we have another 128 characters available.

The idea behind a lot of the character encodings that came next, in particular, the ISO 8859-*, and Windows code pages. The first step towards making ASCII work for other languages is to extend it. Reality is stranger than fiction, now we actually do have an EBCDIC encoder in the Node source tree anyway, because we actually support one of these weird IBM systems, or start supporting them. I was thinking for April Fool's this year, I might want to open a PR against Node that has support for that character encoding, because, again, only supports IBM mainframes.

For example, there's EBCDIC, which is basically only used on IBM mainframes these days. There are other character encodings that historically were concurring with ASCII. There's not a lot else that you can do with it, which is frustrating when you do want to support other languages. It covers most use cases that appear in the English languages and languages that use a similar alphabet, which aren't all that many. It doesn't really matter because the exact values don't matter. I will use hexadecimal representations a lot. We say each of these values will just be encoded as a single byte in the final output. These are the decimal and hexadecimal values that we give them. Not all of these are printable characters that you could see on paper, and we assign each of the numbers. The idea is, we take about 127 characters. At least, historically, it's the most important one of the first character encodings that came into existence.

The simplest version that you can do this is ASCII. What are we going to do about that? ASCII That doesn't work for more complicated use cases like Chinese characters. Once you start working with more characters, that system breaks down because when you say each character is 1 byte, then you're stuck with 256 characters. At least in this case, we take these numbers and say, each of these numbers corresponds to 1 byte in the final output. Each of these characters is being assigned a number. Hello is a five letter word, we will split that into five separate characters. For example, this would be the standard ASCII approach to this. That whole process of going from text to a list of bytes is known as encoding. Then we figure out a way to transcribe those integers into a list of bytes.

We take these characters, we assign them numbers, integers. The idea with character encoding is that the computers definitely would prefer numbers. That's what separates it from random images on paper. Text is conceptually a list of characters.

What is a character encoding? In the end, when people do things with computers, they tend to work in text forms, whether that's programs, or whether that is some other input that they give to the computer. If you can, that's good, because hopefully you'll learn it right now. I don't know who of you can tell why there are these replacement characters just randomly in the middle of the text. This bug has been around for a long time because I gave a talk about this topic in 2017 in March, and they had that bug there already. It's not that long ago, it was earlier this year. This is a screenshot from a Travis CI run that I ran a while back.

For me, specifically, that means that I get to work on Node.js core full time. I work at NearForm, in a department called NearForm Research.
