Hi

what is unicode

Unicode is a character set supported across many commonly used software applications and operating systems.
For example, many popular web browser, e-mail, and word processing applications support Unicode.
Operating systems that support Unicode include Solaris Operating Environment, Linux, Microsoft Windows 2000, and Apple's Mac OS X.

Applications that support Unicode are often capable of displaying multiple languages and scripts within the same document. In a multilingual office or business setting, Unicode's importance as a universal character set cannot be overlooked.

An encoding is the mapping of Unicode code points to a stream of storable code units or octets. The most common encodings include the following:

UTF-8
UTF-16
UTF-32

Why is it Important?

UTF-8 is an important encoding because of the following reasons:

ASCII compatible
easily supported
compact and efficient for most scripts
easily processed, unlike other multibyte encodings
