While I was writing my new article I found out about really cool thing I am going to share with you.
Check out this emoji containing 4 people 👩👩👦👦.
While I was trying to delete 👩👩👦👦 in VSCode using backspace it
didn't disappear, but it just changed to this 👩👩👦. After hitting another backspace it changed to 👩👩 then to 👩 and then it finally disappeared. So it goes
👩👩👦👦 ⌫ 👩👩👦 ⌫ 👩👩 ⌫ 👩 ⌫
Why this happens?
When we look on the decoded symbols, we can see that the symbols are equal to this in hex:
👩👩👦👦: 0x1f469 0x200d 0x1f469 0x200d 0x1f466 0x200d 0x1f466 👩👩👦👦: 0x1f469 0x200d 0x1f469 0x200d 0x1f466 👩👩: 0x1f469 0x200d 0x1f469 👩: 0x1f469
While 0x200d character is a "ZERO WIDTH JOINER" which tells the renderer, that the preceding and following characters should join each other. 🎉
So it is like 👩 + 👩 + 👦 + 👦.
Cool isn't it?
Removing of single woman works as well, so this 👩👦👦 can transformed to the hex code like this: 0x1f469 0x200d 0x1f466 0x200d 0x1f466
