unicode


The term Unicode refers to a standard system of characters created to allow easy handling of computing, visualization and transmission of writings from various languages ​​and technical disciplines, but also includes classic texts from already dead languages. In other words and in a more specific way, Unicode is a common character format, which includes each of the keyboard characters of a computer. According to what has been expressed, the term derives from the three objectives pursued, which are universality, uniqueness and uniformity.

Unicode especially supplies a unique number for each of the characters, without the implication of platform, language, program, which makes it easy to port between different encoding systems and platforms. As can be seen, Unicode does not only cover letters, but also symbols, numbers and others.

A character encoding defines a table that represents characters as numbers. Each character is associated with a number. In Unicode, that number is called a code point. The predecessor of Unicode is known as “ASCII”, with the difference that the latter included only the characters used in the English language.

This standard is supported by the UTC acronym for the Unicode Technical Committee, integrated into the Unicode Consortium, a non-profit organization, in which large and famous companies such as Apple, Microsoft, Google, Yahoo, Adobe are part with different degrees of involvement. , IBM, SAP, Oracle, or entities such as the prestigious University of Berkeley and individual professionals and academics. The Unicode Consortium maintains a very close relationship with ISO/IEC, with which since 1991 it has maintained an agreement to synchronize its standards that contain the same characters and code points.
