What are Unicode characters?

Have you ever sent an emoji in a text message and been baffled when your friend receives it on their phone but not on yours? Or maybe you got a message in a language you don't know yet the characters look entirely alien to you. Unicode characters hold the key to the solution.

Unicode is a text encoding scheme that allows computers to correctly display and interpret text written in any script or language. So what are Unicode characters, precisely, and how do they function in the world of SMS communication?

In this piece, we'll delve into the intriguing world of Unicode characters and their important place in today's digital discourse. Put on your emoji thinking cap, fasten your seatbelt, and prepare to enter the beautiful world of Unicode!

What is the main purpose of Unicode?

What is the main purpose of Unicode

Unicode is a text encoding system that was created to provide a standard character set for use by all scripts and languages. In other words, it's a method for representing characters from any language or script in a format that can be read and understood by computers regardless of their platform or software.

Before Unicode, compatibility concerns arose when text had to be transferred between platforms and devices because different encoding schemes were used for different languages and scripts. If you try to read a document written in a language that uses a different encoding scheme than the one your computer is configured to use, you can see question marks or other symbols instead of the intended text.

Unicode was created to solve this problem by creating a universal encoding system that could be used to represent characters from any and all writing systems and languages. In doing so, it paves the way for unhindered information sharing across a wide variety of systems, platforms, and software programmes, regardless of the underlying language or script.

Emojis, mathematical symbols, and musical notation are just a few examples of the non-standard characters and symbols that can be represented inside the Unicode standard. More freedom of expression and originality in digital communication is made possible because non-linguistic forms of communication can be encoded and conveyed using a standard encoding scheme.

Unicode's overarching goal is to standardise the digital representation of the world's written languages and scripts to facilitate easy and effective communication and data exchange across all networks and devices.

How can you tell if a character is Unicode?

Unicode is a text-encoding standard that accommodates writing systems from all over the world. It might be difficult to tell which characters are Unicode and which are not due to the large number of possible Unicode characters. For assistance in recognising Unicode characters, consider the following:

  • A hexadecimal code for a Unicode character will often begin with the "U+" prefix. The character code for the heart sign is U+2764, for instance.
  • If you're working with a text file, you can see if it uses Unicode by looking at the file's encoding. Generally speaking, the encoding of a file can be determined automatically by most current text editors and word processors and displayed in the file properties.
  • If you're stuck trying to figure out what a certain character is, pull up a character map. The majority of modern OSes include a built-in character map that lets you look up characters using either their Unicode code point or their name.

If you're still unsure whether or not a character is Unicode, there are a few telltale signs to check for within the character itself. Unicode characters can be recognised from non-Unicode characters by sharing a few commonalities:

  • Unicode characters, which require multiple bytes to represent, may appear on some systems as a string of characters because they are multi-byte characters.
  • Unicode characters can have a value greater than 128 in ASCII-based character sets since they are represented utilising the higher bits of a byte.

In general, it's safer to presume a character is Unicode than to risk mistyping it. Unicode is used widely in modern communication, therefore understanding how it is encoded and represented is becoming more and more crucial.

What is the most common Unicode?

Unicode is an extensive and varied system for encoding text, with more than 143,000 characters and counting. Still, certain symbols are far more typical than others. Some of the most frequently seen Unicode characters are as follows:

  • Standard letters and numbers used by most Western languages can be found in Unicode's Basic Latin range. Whether it's an email or a text message, these symbols are the backbone of the digital world's written communication.
  • Emojis: Emojis have become a standard part of digital communication, allowing us to convey a wide range of feelings and ideas with a single image. The thumbs up, the heart, and the crying laughter emojis are some of the most frequently used emojis.
  • The Chinese, Japanese, and Korean character set (CJK) is one of the largest and most intricate in Unicode. It has hundreds of kanji, hiragana, katakana, and hanzi characters, all of which are used in East Asian languages.
  • Punctuation marks: The Basic Latin range of Unicode also includes punctuation marks like the period (. ), comma (, ), and exclamation mark (!) that are often used in written communication.

Basic written communication symbols and digital culture icons like emojis make up the bulk of the most frequently used Unicode characters. But, because to Unicode's extensive character set, there is always something new to learn and investigate.

How do Unicode characters work?

How do Unicode characters work

For Unicode characters to function, they are each given their own code point and encoded in a standardised method so that they can be read and understood by a wide variety of computers and programmes.

Unicode Text Encoding (UTF-8) is one of several encoding systems for displaying Unicode characters. The number of bytes needed to represent each character is set by these formats; UTF-8 is the most popular format for websites and text files.

For each Unicode character, there is a corresponding code point that is used to seek up the character in a table that translates code points into their encoded representation. Thereafter, the encoded representation is utilised to either show or process the character as needed.

Unicode characters facilitate interaction and information sharing across various platforms. Due to Unicode's status as an industry-wide standard for expressing text, any computer or software application that supports Unicode will be able to read and properly understand text encoded in Unicode, regardless of the language or script it was originally written in.

As a whole, Unicode characters offer a standardised method of text encoding that facilitates easy interaction and information sharing across a wide variety of media and languages. Unicode has become a crucial component of contemporary digital communication by providing a universal encoding strategy for all writing systems and languages.

Unicode characters in SMS messaging

Unicode characters in SMS messaging

Unicode characters play a crucial part in making it possible to express a wide range of ideas and feelings in a single text message via SMS, which is one of the most common ways of communication in the world.

Because the conventional GSM character set is limited to 7-bit characters, Unicode characters are used to represent characters that are not included in SMS communications. This paves the way for the use of emojis, special characters, and non-Latin scripts in SMS.

There are, however, restrictions on how Unicode characters can be used in SMS. Unicode characters can take up more room in a text message than regular GSM characters do since they require more bytes to represent. Sending a message containing a large number of Unicode characters may result in the message being broken up into several portions, which may be confusing to the recipient.

However, not all mobile devices and carriers support Unicode characters in SMS texting, which can lead to compatibility concerns when sending and receiving messages across platforms and networks.

Unicode characters, despite these constraints, have become an integral feature of SMS messaging, enabling greater expression and innovation in digital communication. Unicode characters have become a vital part of our daily communication, from the heart emoji to the thumbs up, making it easier to express ourselves and connect with people in the digital world.



Finally, Unicode characters are an intriguing and necessary component of today's sophisticated communication systems. They enable for the depiction of all writing systems and languages, as well as special letters and symbols, making it possible for us to communicate a wide range of ideas and emotions via digital communication.

Unicode has become a vital component of our daily communication, allowing us to connect and share information across various platforms and devices, from the simple love emoji to the complicated letters of East Asian languages.

Unicode has many advantages, but it also has some negatives, such as the fact that it might interfere with SMS communications and cause compatibility problems between operating systems. Unicode, which provides a global standard for encoding text, has become an indispensable tool for international digital communication and cooperation.

Remember the magic of Unicode characters the next time you send an emoji in a text message or come across a character from a foreign language. There's no doubt that Unicode will play an even larger role in facilitating our ability to communicate and share ideas with one another as the world becomes even more interconnected and diverse.
