You might have seen emoji in some websites’ browser title bar. I have not talking about the favicon. I am taking about emoji, thats what you see in browser tab right after favicon or anywhere in webpage.
This is what I am talking, you see the sun emoji in the browser tab.

How to do it:
- Find an emoji. eg: Go to https://emojipedia.org/ search and find a emoji. Copy it.
- Open you webpage which supports unicode. (Notepad++, VSCode etc)
- Paste the emoji you copied, in the
head > title tag. - Important step: Add the below meta tag inside your head tag.
<meta charset="UTF-8" />
You code will now look like this.

Thats it, save and open in browser. Your browser tab should display the emoji.
Peace ✌️
