A standardized system for representing characters and symbols from various writing systems across the world, including ancient and modern scripts, technical symbols, and punctuation.

Unicode encompasses a vast collection of characters from diverse writing systems, including Cherokee, Imperial Aramaic, Old Hungarian, Egyptian hieroglyphs, and even alchemical symbols.

Emojis, originating from Japanese mobile phones, are pictorial symbols that are now widely used worldwide to express emotions, feelings, or activities.

Unicode currently supports over 3,700 unique emojis, encompassing various categories like faces, weather, animals, and icons representing diverse actions and emotions.

The number of unique emojis supported by Unicode is constantly growing and evolving, reflecting the ongoing development of standardized character sets.

To promote inclusivity and avoid bias, the general recommendation for emojis depicting people or body parts is to use neutral or generic depictions with non-realistic skin tones like orange.

Unicode is a universal character encoding standard that provides a comprehensive system to represent, process, and exchange written text across different languages, platforms, and software.

Unicode's vast character coverage and ongoing updates ensure that it can accommodate the changing needs of digital communication and representation, guaranteeing future-proof support for diverse languages and symbols.

A standard character set defined by ISO. The current version is ISO/IEC 10646:2020.

The range of integers used to represent characters in a character set.

A specific integer value that represents a character within a character set.

The standard for representing characters in computers and other devices. It uses code points to represent characters from different languages and scripts.

A non-profit organization responsible for developing and maintaining the Unicode standard.

Additional characters that can be added to some emoji to specify their skin tone.

Properties associated with characters in Unicode, such as its category, script, and numerical value.

A representation of a character in Unicode using hexadecimal notation with a "U+" prefix.

A unique identifier for a character, like "LATIN CAPITAL LETTER A" or "BLACK STAR". It is a string associated with a specific Unicode code point.

The Unicode character database that contains information about character properties, like their name, general category, and casing.

A numerical representation of a character in Unicode, written in hexadecimal format (e.g., U+0041 for the letter 'A').

A visual representation of a character, like the image of a letter or symbol on a screen or printed page.

A subdivision of the codespace, containing 65,536 code points. There are 17 planes in the codespace.

A named group of consecutive code points within a plane. Blocks group together characters used in a similar writing system or for a specific category.

The first plane in the codespace, containing the first 65,536 code points (U+0000 to U+FFFF). It includes common characters used in many modern languages.

A specific integer value that represents a character within a character set.

The range of integers used to represent characters in a character set.

In GTK+ applications on Linux, you can enter Unicode characters by typing ctrl + + U followed by the hexadecimal Unicode code point.

A non-profit organization responsible for developing and maintaining the Unicode standard.

A program that converts characters between different encodings.

It displays a list of supported character encodings and can convert text files from one encoding to another.

A command-line tool to convert text files between different character encodings.

In programming, a string is a sequence of characters, such as letters, numbers, and symbols, treated as a single unit. It represents textual data and is enclosed within quotation marks.

Escape sequences are special character combinations used within strings to represent characters that are difficult or impossible to type directly, such as newlines, tabs, and special symbols.

A Unicode escape sequence is a way to represent Unicode characters within text using a special code format starting with '\u' followed by four hexadecimal digits.

A hexadecimal number system uses base-16, with digits 0-9 and A-F representing values from 0 to 15. It's commonly used in computer systems.

In some programming languages, a backslash followed by a sequence of up to six hexadecimal digits enclosed in curly braces can represent a Unicode character.

Character references are a way to represent Unicode characters within XML and HTML files using special codes starting with '&#' followed by either decimal or hexadecimal digits.

Named character references are a way to represent specific Unicode characters within HTML using predefined names like '&' for the ampersand symbol.

The Unicode Transformation Format (UTF) is a family of character encoding forms supporting all characters in the Unicode standard, including all the world's writing systems.

UTF-32 represents each Unicode character using 4 bytes, making it simple and efficient for processing. However, its fixed-width nature uses more storage space.

UTF-16 uses either 2 or 4 bytes per character, optimized for encoding characters within the Basic Multilingual Plane (BMP). This makes it generally efficient for text, but the variable width can be slightly less efficient for processing.

UTF-16 uses 2 bytes for characters within the Basic Multilingual Plane (BMP) and 4 bytes for characters outside of the BMP.

UTF-8, using 1 to 4 bytes per Unicode character, prioritizes compactness, especially for English text. However, it can be less efficient for languages like Chinese, Japanese, and Korean that use many characters outside the ASCII range.

UTF-8 represents English characters (ASCII) using a single byte, while other characters use more bytes as needed.

UTF-8 is the most common text encoding because it is flexible and compact, using fewer bytes on average. It balances efficiency and memory usage.

UTF-8 can be less efficient for languages like Chinese, Japanese, and Korean because these languages use many characters outside the Basic Multilingual Plane (BMP), requiring more bytes per character.
