Unicode Encoding Conversion Tool

Frequently Asked Questions

What is Unicode?

Unicode is a universal character encoding standard that assigns a unique code to every character, regardless of platform, program, or language.

Why is Unicode important?

Unicode ensures consistent encoding, representation, and handling of text, enabling seamless communication and data exchange across different systems and languages.

How do I use Unicode?

You can use Unicode by referencing its code points in your applications or by using tools that support Unicode encoding.

How does Unicode work?

Unicode assigns a unique numeric value, called a code point, to each character. These code points are written in the format "U+XXXX", where "XXXX" is a hexadecimal number. For example, the code point for the letter "A" is U+0041.

What are Unicode blocks?

Unicode organizes characters into blocks based on their scripts or usage. For example, the "Basic Latin" block contains characters used in English, while the "CJK Unified Ideographs" block contains Chinese, Japanese, and Korean characters.

What is UTF-8 and how is it related to Unicode?

UTF-8 is a variable-length character encoding for Unicode. It encodes each Unicode character as one to four bytes, making it efficient for text that primarily uses ASCII characters while still supporting all Unicode characters.

How to convert text to Unicode in different programming languages?

Here are examples of converting text to Unicode in various programming languages.

Java

String text = "A";
String unicode = String.format("\\u%04x", (int) text.charAt(0));
System.out.println(unicode); // Output: \u0041

PHP

$text = "A";
$unicode = sprintf("\\u%04x", ord($text));
echo $unicode; // Output: \u0041

Go

package main

import (
	"fmt"
)

func main() {
	text := "A"
	unicode := fmt.Sprintf("\\u%04x", text[0])
	fmt.Println(unicode) // Output: \u0041
}

C

#include <stdio.h>

int main() {
    char text = 'A';
    printf("\\u%04x\\n", text); // Output: \u0041
    return 0;
}

JavaScript

const text = "A";
const unicode = "\\u" + text.charCodeAt(0).toString(16).padStart(4, "0");
console.log(unicode); // Output: \u0041

TypeScript

const text: string = "A";
const unicode: string = "\\u" + text.charCodeAt(0).toString(16).padStart(4, "0");
console.log(unicode); // Output: \u0041

Python

text = "A"
unicode = f"\\u{ord(text):04x}"
print(unicode)  # Output: \u0041
