Quickly find out how long your UTF-8 string is, including how many characters it contains as well as its size in byte(s).

This tool helps you when you want to find out how long your string is as to not exceed input limits or simply measure the size of a particular string.

When we talk about the "size" of a UTF-8 string, we mean 2 things: the length and size of a string. Let's break it down a bit:

1. String Length - Length refers to the number of characters in a string. In UTF-8, characters can vary in size, but the length is just how many characters are in the string, no matter how complex or simple they are. For example, the word "Hello" has 5 characters, so the length is 5.

2. String Size - Now, size refers to how much space (in bytes) the string takes up on a computer. In UTF-8, characters can take up different amounts of space depending on that specific character itself. Simple English characters like "a" take up 1 byte, whereas symbols, emojis or characters from other languages (like "é" or "€") may take up to 2, 3, or even 4 bytes of space.

In essence, a UTF-8 string length refers to the number of characters you see and the size, is about the amount of memory or space the characters use.
