Unicode

Unicode

In Linux, Unicode is a character encoding standard that allows computers to represent and manipulate text from various writing systems, including alphabets, ideographs, and symbols, by assigning a unique numeric value to each character.

Here's a more detailed explanation:

What is Unicode?

Unicode, or the Universal Coded Character Set (UCS), is a standard that aims to provide a single character set encompassing all the characters used in the world's writing systems.

What is its Purpose?

It solves the problem of dealing with multiple character sets used for different languages by providing a universal way to represent text.

How it works?

Unicode assigns a unique code point (a number) to every character, regardless of the platform, program, or language.

How Unicode is Encoded?

Unicode text is processed and stored as binary data using encodings like UTF-8, which defines how to translate the standard's abstracted codes for characters into sequences of bytes.

What are the Benefits?

Unicode allows for the easy exchange and display of text in different languages and scripts without ambiguity, making it essential for internationalization and globalization of software and content.

For Example
The word "Hello" can be represented in Unicode as U+0048 U+0065 U+006C U+006C U+006F, where each U+xxxx represents a unique character code point.

Unicode in Linux
Linux systems fully support Unicode, allowing users to input, display, and process text in various languages and scripts.

Unicode Input
Unicode input methods allow users to enter characters not directly supported by a physical keyboard, such as by selecting them from a display, typing a sequence of keys, or drawing the symbol.

Unicode Input Tools
Several tools, like KCharSelect, are available for Unicode input, allowing users to select and insert characters from the Unicode character set.

UTF-8
Python Docs often defaults to using UTF-8, a common encoding for Unicode, which uses 8-bit values to represent characters.
