Unicode 6.0.0 Unicode 6.0.0 is a major version of the Unicode Standard and supersedes all previous versions. This is the official guide about UNICODE standard, with each chapter printed in a PDF file ( see the menu on your left ). The Unicode Standard is the universal character encoding standard for written characters and text. With Unicode, the information technology industry has replaced proliferating character sets with data stability, global interoperability and data interchange, simplified software, and reduced development costs. While taking the ASCII character set as its starting point, the Unicode Standard goes far beyond ASCII’s limited ability to encode only the upper and lowercase letters A through Z. It provides the capacity to encode all characters used for the written languages of the world: more than 1 million characters can be encoded ( 1,114,112 to be more precise ). The Unicode Standard specifies a numeric value ( code point ) and a name for each of its characters. In this respect, it is similar to other character encoding standards from ASCII onward. In addition to character codes and names, other information is crucial to ensure legible text: a character’s case, directionality, and alphabetic properties must be well defined. Unicode characters are represented in one of three encoding forms: a 32-bit form ( UTF-32 ), a 16-bit form ( UTF-16 ), and an 8-bit form ( UTF-8 ). The 8-bit, byte-oriented form, UTF-8, has been designed for ease of use with existing ASCII-based systems.
