As we know, Unicode is a universal character encoding system that assigns a unique code point to every character, symbol, or emoji, ensuring consistent representation across all devices and platforms. Emojis, too, are nothing more than special Unicode characters that browsers visually render as images. In HTML, emojis can be inserted either directly as characters or using their respective Unicode escape sequences (e.g., 😀 for 😀). While they appear as colorful icons, behind the scenes, they are simply text with assigned code points. Today, over 90% of websites use Unicode (UTF-8) encoding, highlighting its critical role in maintaining multilingual and emoji-rich content across the web.
Note: Emojis are just special Unicode characters displayed as images.
