• This question is part of the Information Technology (IT) or Computer Science subject, specifically under the Data Representation or Character Encoding section.
Why "Unicode" is used:
In the early days of computing, different systems used different codes for characters (like ASCII). This caused problems because a document created on one computer might look like gibberish on another, especially if it used non-English characters.
Unicode was created to solve this by providing a unique number for every character, no matter the platform, program, or language.
Universal Coverage: It includes characters for almost all living languages (English, Hindi, Chinese, Arabic, etc.), as well as historical scripts, mathematical symbols, and even emojis.
Unique Identification: Each character is assigned a "code point" (a specific number). For example, the letter 'A' is always represented by the same numerical value globally.
Consistency: It ensures that data can be transported through many different systems without corruption.
