UTF8 Encode Decode

UTF8 Converter

UTF-8 converter helps you convert between Unicode character numbers, characters, UTF-8 code units in hex, percent escapes,and numeric character references.

How to convert to UTF8

1. Enter your text in the editor at the top.
2. You will automatically get UTF8 bytes at the bottom.
3. You can also import text files for conversion

Utf8 To Ascii Converter - Convert Unicode Character Codes to ASCII

UTF8 is also known as Unicode or Unicode Transformation Format. UTF8 is an encoding scheme for representing characters in computer files. IBM designed it in 1991 to allow computers to read any character set defined by ISO 10646.

This tool converts any Unicode character code into its corresponding ASCII equivalent. If you need to convert Unicode character codes to ASCII, use this free online tool. You will find that it works well with both Windows and Mac operating systems.

This section will show you how to convert Unicode character codes into corresponding ASCII characters.

To convert Unicode character codes (UTF8) to ASCII, you must first understand what each code means. A Unicode character code consists of two parts: an integer value and a modifier. The integer value represents the number of bytes required to represent the character, and the modifier indicates whether the character is upper case or lower case.

Create a new file called utf8_to_ascii.php.
This script will take any string containing UTF8 characters and return them in ASCII format. It does not require any additional libraries or modules.

Paste the following code into it.

$utf8 = "This is a test";

$ascii = utf8_to_ascii($utf8);

The output should be:

This is a test
<?php echo htmlspecialchars($utf8)?>

UTF-8

UTF-8 translates Unicode data using a mathematical process that encodes the data using 8 data bits, retains all ASCII codes from 00 to 7F encoded as itself, and only contains nulls when they are the intended characters.

For example, the Unicode string "ABC" is "004100420043"x. In UTF-8, however, it is "414243."

UTF8 is used to store Unicode on various UNIX platforms and is the default encoding for most new internet standards because it allows Unicode data to transit over an 8-bit network without the network needing to know it is Unicode.

What are Unicode encodings UTF-8, UTF-16, and UTF-32?

We now know that Unicode is an international standard that encodes every known character to a unique number. But, how do we move these unique numbers around the internet? Transmission is achieved using bytes of information.

UTF-8: Every code point is encoded using one, two, three, or four bytes in UTF-8. It is ASCII backward compatible. All English characters use only one byte, which is exceptionally efficient. If we're sending non-English characters, we'll merely need more bytes.  It is the most used type of encoding, and Python 3 uses it by default. The default encoding in Python 2 is ASCII (unfortunately).
UTF-16 UTF-16 has a variable length of 2 or 4 bytes. Because most Asian text can be encoded in two bytes each, this encoding is ideal for it. It isn't very good for English since every English character requires two bytes..
UTF-32 is fixed 4 bytes. All characters are encoded in 4 bytes, so it needs a lot of memory. It is not used very often. 
 

Why is UTF8 Encode relevant today?

UTF-8 is a character encoding format that is widely used today. It remains relevant because it allows computers to store and transmit text in a way that a wide range of devices and applications can understand.

Here are a few reasons why UTF-8 encoding is still relevant today:

1. Multilingual support: UTF-8 supports various characters from different languages, including alphabets, ideographs, and symbols. It can handle text in most of the world's languages, making it an essential encoding format for global communication and collaboration.
2. Compatibility: UTF-8 is compatible with ASCII, the most common character encoding format used in the early days of computing. This backward compatibility makes it easy to work with legacy systems that use ASCII while supporting newer characters.
3. Web standard: UTF-8 is the World Wide Web Consortium (W3C) recommended encoding for web pages. This means that most modern web browsers support it natively, and it is widely used in web development.
4. File format: UTF-8 is commonly used as a file format for storing and exchanging data, especially in international contexts. It is the default encoding format for many programming languages and software tools, making it a crucial part of the modern computing ecosystem.

In short, UTF-8 encoding remains relevant today because it enables the exchange of text in multiple languages, is compatible with legacy systems, is a web standard, and is widely used as a file format.
