What is Unicode?
'''Unicode''' is a [[standard]], promoted by the [[Unicode Consortium]], for [[character encoding|encoding]] the text of most of the world's writing systems, using [[variable-width encoding]]s, such as UTF-8. Its goal is to replace current and previous [[character encoding]] standards with one worldwide standard for all languages. It has already done that to a large degree; for example, it is dominant on the web, in the form of the UTF-8 encoding. UTF-16 is also common, for example, on Windows, while Microsoft recommends UTF-8. The standard supports [[emoji]]s and other symbols that older standards did not support. Older standards such as the [[Émile Baudot]] code were made for European languages and could not represent all languages of the world, for example, Chinese or Japanese. They also could not represent languages such as Arabic or Hebrew, which are written from right to left—at least not when mixed with other languages that are written from left to right. Unicode supports such mixing. It also allows for sorting (collating), which is not easy when languages are mixed. Unicode provides many printable characters, such as letters, digits, [[diacritic]]s (things that attach to letters), and punctuation marks. It also provides characters that do not actually print, but instead control how text is processed. For example, a [[newline]] and a character that makes text go from right to left are both characters that do not print. == Details == Unicode, formally the Unicode Standard, is an information technology standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard, as of Unicode 14.0 defines 144,697 characters covering 159 modern and historic scripts, as well as symbols, emoji, and non-visual control and formatting codes. Unicode is promoted by the [[Unicode Consortium]] and based on [[International Organization for Standardization|ISO]] standards. New versions are issued every few years and later versions have over 144,000 charact
