Unicode

From Rosetta Code
Revision as of 18:14, 3 August 2011 by rosettacode>Mwn3d (I don't think "Unicode" is an acronym ("Unique Numeric Indicators for the Communication Of Display Entities"?))
This page is a stub. It needs more information! You can help Rosetta Code by filling it in!

Unicode is a mapping from characters in a very large set of languages to code points, together with a set of descriptive metadata about those code points (so that you can know whether they are alphabetic, numeric, symbolic, white-space, etc.)

A number of different mechanisms are used for mapping this to a sequence of bytes. The single most important one (because it embeds ASCII and so is easy to deploy on existing systems) is UTF-8.
