Unicode
Unicode is the universal character encoding standard maintained by the Unicode-Consortium. It provides a unique code point for every character, regardless of the computing platform, device, application, or language. This consistency is vital for the global exchange of text and the development of software that supports Internationalization and Localization. Before the widespread adoption of Unicode, character sets like ASCII and various ISO-8859 standards were used, but they lacked the capacity to represent all global scripts simultaneously.
The standard supports multiple encoding forms, with UTF-8 being the most dominant on the World Wide Web due to its space efficiency and backward compatibility with ASCII. Other common formats include UTF-16, used internally by systems like Windows and Java, and UTF-32. The repertoire of Unicode characters includes not only modern and historical scripts but also mathematical symbols, control characters, and Emojis. Technical details regarding the latest version of the standard can be found at the Unicode Consortium Official Site and historical context is available on Wikipedia.
By unifying text representation, Unicode ensures that a document created in one part of the world can be transmitted and viewed in another without the risk of character corruption, often referred to as mojibake. Its continuous evolution allows for the inclusion of newly discovered historical scripts and the ever-expanding set of Emojis used in modern communication.
