What is unicode?

Unicode is a universal character encoding standard. It defines the way individual characters are represented in text files, web pages, and other types of documents.
Unlike ASCII, which was designed to represent only basic English characters, Unicode was designed to support characters from all languages around the world. The standard ASCII character set only supports 128 characters, while Unicode can support roughly 1,000,000 characters. While ASCII only uses one byte to represent each character, Unicode supports up to 4 bytes for each character.


Unicode is a computing standard for the consistent encoding, representation and
handling of text expressed in most of the world's writing systems. Fundamentally,
computers just deal with numbers. They store letters and other symbols by assigning
a number for each one. In order for a computer to be able to store text and symbols
that human can understand, there needs to be a code that transforms characters or
the symbols into numbers.
