What happens when we theoretically run out of all the space we had to encode character? Also how are new characters added to unicode?
@ComputerScienceLessons5 ай бұрын
An organisation called the Unicode Consortium decided what new characters to include. Once or twice a year, new characters are introduced. It's unlikely we're are going to run out of space soon but, theoretically the same system could be scaled up again and again. home.unicode.org/ :)KD

I wonder why ASCII was 7 bits in the first place? In the end this played well with UNICODE UTF-8 fitting into a byte format. Was it because of the teletype selector vanes?
@ComputerScienceLessons4 жыл бұрын
I think it was because 7 was enough to cover all of the characters on a (teletype) keyboard and it left a spare bit to be used for parity checking. A lucky accident perhaps? :) KD

When you show a number of possible encodings in UTF-8 for 2-byte scenario why don't you add 1024 to 937? The same question goes for the 3-byte scenario. For some reason you don't add possible combinations for the last 2 "free" bits.

The goals starting from 6:41 are actually not entirely correct. Unicode is “kinda” compatible with ASCII, in the sense that Unicode codepoint 65 (A) corresponds to ASCII code 65(A), for example. However, Unicode does not mandate that codepoint 65 is *necessarily* stored as 1-byte code 65. This is a goal of UTF-8 instead. UTF-16 and UTF-32 comply with Unicode standard but don’t store codepoint 65 as a 1-byte value. This video makes the same mistake multiple times, conflating Unicode and UTF-8, which are broadly speaking unrelated to each other and serve completely different purposes.
@justcurious19402 жыл бұрын
yea brother i watched this video few days ago before i knew anything about this topic but after i have learned more about it i can see how much wrong informations on it unicode is the collection of code points that represent characters UTF-8 or UTF-16 or UTF-32 is the representation of these code points in memory so UTF-8 is a way to encode unicode using a multibyte encoding scheme UTF-32 is fixed size in memory i think i'm still searching about UTF-16 to understand is it represented in memory ....
