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.

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.

What is UTF-8 Encoding?

Text: its importance on the internet goes without saying. It’s the first “T” in “HTTP”, the only “T” in “HTML”, and virtually every website uses it somehow, be it a URL, a piece of marketing copy, a product review, a viral Tweet, or a blog post. (Hi there!)
But, web text might not actually be as simple as you think. Consider the thousands of languages spoken today, or all the punctuation and symbols we can add to enhance them, or the fact that new emojis are being created to capture every human emotion. How do websites store and process all of this?
The truth is, even something as basic as text requires a well-coordinated, clearly-defined system to appear in web browsers. In this post, I’ll explain the basics of one technology central to text on the web, UTF-8. We’ll learn the basics of text storage and encoding, and discuss how it helps put engaging words across your site.

What Is UTF-8?

UTF-8 stands for “Unicode Transformation Format — 8 bits.” That’s not helpful to us yet, so let’s rewind to the basics.

Binary: How Computers Store Information

In order to store information, computers use a binary system. In binary, all data is represented in sequences of 1s and 0s. The most basic unit of binary is a bit, which is just a single 1 or 0. The next largest unit of binary, a byte, consists of 8 bits. An example of a byte is “01101011”.
Every digital asset you’ve ever encountered — from software to mobile apps to websites to Instagram stories — is built on this system of bytes, which are strung together in a way that makes sense to computers. When we refer to file sizes, we’re referencing the number of bytes. For example, a kilobyte is roughly one thousand bytes, and a gigabyte is roughly one billion bytes.
Text is one of many assets that computers store and process. Text is made up of individual characters, each of which is represented in computers by a string of bits. These strings are assembled to form digital words, sentences, paragraphs, romance novels, and so on.

ASCII: Converting Symbols to Binary

The American Standard Code for Information Interchange (ASCII) was an early standardized encoding system for text. Encoding is the process of converting characters in human languages into binary sequences that computers can process.
ASCII’s library includes every upper-case and lower-case letter in the Latin alphabet (A, B, C…), every digit from 0 to 9, and some common symbols (like /, !, and ?). It assigns each of these characters a unique three-digit code and a unique byte.

Unicode: A Way to Store Every Symbol, Ever

Enter Unicode, an encoding system that solves the space issue of ASCII. Like ASCII, Unicode assigns a unique code, called a code point, to each character. However, Unicode’s more sophisticated system can produce over a million code points, more than enough to account for every character in any language.
Unicode is now the universal standard for encoding all human languages. And yes, it even includes emojis.
So, we now have a standardized way of representing every character used by every human language in a single library. This solves the issue of multiple labeling systems for different languages — any computer on Earth can use Unicode.
But, Unicode alone doesn’t store words in binary. Computers need a way to translate Unicode into binary so that its characters can be stored in text files. Here’s where UTF-8 comes in.

UTF-8: The Final Piece of the Puzzle

UTF-8 is an encoding system for Unicode. It can translate any Unicode character to a matching unique binary string, and can also translate the binary string back to a Unicode character. This is the meaning of “UTF”, or “Unicode Transformation Format.”
There are other encoding systems for Unicode besides UTF-8, but UTF-8 is unique because it represents characters in one-byte units. Remember that one byte consists of eight bits, hence the “-8” in its name.
More specifically, UTF-8 converts a code point (which represents a single character in Unicode) into a set of one to four bytes. The first 256 characters in the Unicode library — which include the characters we saw in ASCII — are represented as one byte. Characters that appear later in the Unicode library are encoded as two-byte, three-byte, and eventually four-byte binary units.

How to convert UTF-8, UTF-16, UTF-32

What is Unicode?

Unicode is a character encoding system that assigns a code to every character and symbol in the world’s languages.
Unicode is the only encoding system that ensures you may get or combine data using any combination of languages because no other encoding standard covers all languages. XML, Java, JavaScript, LDAP, and other web-based technologies all require Unicode.
UTF-8, a variable length encoding method in which one represents each written symbol- to four-byte code, and UTF-16, a fixed width encoding scheme in which a two-byte code represents each written symbol, are the two most prevalent Unicode implementations for computer systems.

Why Use Unicode?

Unicode can handle data in a variety of scripts, including French, Japanese, and Hebrew. Before Unicode was introduced, a computer could only process and show the written symbols on its operating system code page, which was connected to a single script.
For example, a computer that can handle French will not be able to process Japanese or Hebrew.

UTF Encoding Forms

Unicode characters are encoded in one of three ways: a 32-bit form (UTF-32), a 16-bit form (UTF-16), or an 8-bit form (UTF-8) (UTF-8).
The identification of each character and its numeric value (code position) is defined by these character encoding standards and how they are represented in bits.

Code Points vs. Code Units

• Code points are numbers that represent Unicode characters. «A code point is the atomic unit of information. Text is a sequence of code points. Each code point is a number which is given meaning by the Unicode standard.»
• Code units are numbers that encode code points to store or transmit Unicode text. One or more code units encode a single code point. Each code unit has the same size, which depends on the encoding format that is used. The most popular format, UTF-8, has 8-bit code units.

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.
