Unicode is an entirely new idea in setting up binary codes for text or script characters. Officially called the Unicode Worldwide Character Standard, it is a system for "the interchange, processing, and display of the written texts of the diverse languages of the modern world." It also supports many classical and historical texts in a number of languages.
Currently, the Unicode standard contains 34,168 distinct coded characters derived from 24 supported language scripts. These characters cover the principal written languages of the world.
Additional work is underway to add the few modern languages not yet included.
Also see the currently most prevalent script or text codes, ASCII and extended binary-coded decimal interchange code (EBCDIC).
