How Do JavaScript Strings Handle Unicode Characters? Have you ever wondered how JavaScript manages complex characters like emojis and symbols in web development? In this detailed video, we’ll explain everything you need to know about how JavaScript handles Unicode characters within strings. We’ll start by discussing how strings are stored as sequences of UTF-16 code units and what this means for representing characters outside the Basic Multilingual Plane. You’ll learn about surrogate pairs and how they affect string manipulation. We’ll explore how methods like charCodeAt() and codePointAt() differ in their handling of characters, especially those made up of two code units. Additionally, we’ll show you how to include Unicode characters in your code using various escape sequences, including the modern \u{X…XXXXXX} syntax for full Unicode support. If you’ve ever been confused by string length or indexing with emojis, this video will clarify why counting characters can be tricky and how to work around it. We’ll also demonstrate how to create full characters from code points using String.fromCodePoint(), ensuring your strings display correctly across different scenarios. Whether you’re working with international text, emojis, or special symbols, understanding how JavaScript processes Unicode makes your coding more reliable and your web applications more user-friendly.
