Unicode
In the late 1980s and early 1990s Xerox, Apple, Microsoft, and others begin working on a new way to
represent characters. The early idea was to widen the existing character set to 16 bits, to allow 65,536
code points. It was originally thought that this would cover the vast majority of characters in modern
languages. This technique was known as UCS-2 but was found to be too large and limiting. This
eBook
required creating a better and more flexible method for encoding characters, we call that UTF-8.
The Unicode Consortium is a collection of many of the largest companies in the tech world. Members
include: Apple, Oracle, IBM, Microsoft, Google and others. The Unicode specification is a living
document that is being revised on a regular basis. The Unicode 11.0 specification even defines code
points for 1644 emojis.
