Unicode has a certain ammount of duplication due to aiming to allow legacy encodings to be converted to unicode without losing any information. In computing, Unicode provides an international standard which has the goal of providing the means to encode the text of every document people want to store on computers. ... In computer science, duplication of data or objects involves copying data byte by byte and, if needed, changing metadata about objects. ...

CJK fullwidth forms

In traditional CJK encodings characters usually took either a single byte (known as halfwidth) or two bytes (known as fullwidth). Characters that took a single byte were generally displayed at half the width of those that took two bytes. Some characters such as the latin alphabet were available in both halfwidth and fullwidth versions. As the halfwidth versions were more commonly used they were generally the ones mapped to the standard code points for those characters. Therefore a seperate section was needed for the fullwidth forms to preserve the distinction. CJK is a collective term for Chinese, Japanese, and Korean, which comprise the largest of East Asian languages. ... A byte is commonly used as a unit of storage measurement in computers, regardless of the type of data being stored. ... The Latin alphabet, also called the Roman alphabet, is the most widely used alphabetic writing system in the world. ...

Greek

Many Greek letters are used as technical symbols. All of the Greek letters are encoded in the Greek section of Unicode but many are encoded a second time under the name of the technical symbol they represent. Of these, micro sign is in the Latin-1 range and most of the rest are in the Letterlike Symbols range. The "micro sign" (U+00B5, µ) is obviously inherited from ISO 8859-1, but the origin of the others is less clear. Technical note: Due to technical limitations, some web browsers may not display some special characters in this article. ... Micro sign (µ, ) is the Unicode character U+00B5. ... ISO 8859-1, more formally cited as ISO/IEC 8859-1 or less formally as Latin-1, is part 1 of ISO/IEC 8859, a standard character encoding defined by ISO. It encodes what it refers to as Latin alphabet no. ... ISO 8859-1, more formally cited as ISO/IEC 8859-1 or less formally as Latin-1, is part 1 of ISO/IEC 8859, a standard character encoding originally developed by ISO, but later jointly maintained by ISO and IEC. The standard, when supplemented with additional character assignments, is the...

Roman numerals

Unicode has a number of characters specifically designated as Roman numerals, as part of the Number Forms range from U+2160 to U+2183. For example, MCMLXXXVIII could alternatively be written as ⅯⅭⅯⅬⅩⅩⅩⅧ. This range includes both upper- and lowercase numerals, as well as pre-combined glyphs for numbers up to 12 (Ⅻ or XII), mainly intended for the clock faces for compatibility with non–West-European encodings. The pre-combined glyphs should only be used to represent the individual numbers where the use of individual glyphs is not wanted, and not to replace compounded numbers. Similarly precombined glyphs for 5000 and 10000 exist. In computing, Unicode provides an international standard which has the goal of providing the means to encode the text of every document people want to store on computers. ... The system of Roman numerals is a numeral system originating in ancient Rome, and was adapted from Etruscan numerals. ... The term compatibility has the following meanings: In telecommunication, the capability of two or more items or components of equipment or material to exist or function in the same system or environment without mutual interference. ...
