As we'll see, Unicode took the first 128 characters from ASCII and built on top of it, offering more than a million characters. But luckily, the problem is not as prominent today because of Unicode. The rise of the internet accelerated this problem. Because code points that require more than 7 bits could differ, making the decoding incorrect. ![]() Now, this was fine when you only worked with your computer, but once you start exchanging strings between computers, you'd be in trouble. So, people would use that extra bit for other characters from languages like Icelandic, Greek, etc. The reason for that is because computers, at the time, offered 8 bits. Yet, at the same time, it caused problems because it being 7-bit meant that 1-bit was left unused. Then eventually, the 7-bit ASCII charset was introduced and became widely adopted. Nevertheless, the first charsets (used for computers) like BCD and the Fortran Character Set were only 6 bits. For instance, a 7-bit character set means that it can provide 2^7 (128) characters. They come in different sizes, like 7-bit, 8-bit, and so on. Although we don't have to create a new system, considering there already are plenty of character sets (abbreviated as charsets) out there.Ī charset is a set of characters that maps to unique code points (numeric values). Then, we could keep going like this and eventually end up with a whole system that maps numbers to characters. For instance, we can determine that 0001 symbolizes A and that 0002 equals B. In other words, we may assign numbers to characters. ![]() But by using binary code we can represent different characters with 1s and 0s.
