Unicode: Unicode Standards
built 655 days ago
You have now seen some of the capabilities that Unicode offers. The sections that follow delve deeper into Unicode's functions to provide helpful information as you work with Unicode Standards and encodings. For instance, what is the function of byte-order marks (BOMs)? What are surrogate pairs, and how do they enable you to go from encoding 65,000 characters to over 1 million additional characters? These and other questions will be explored in the following sections.

The Internationalization & Unicode Conference is the premier technical conference for both software and Web internationalization as well as a great opportunity for networking with other practitioners. IUC 30 is your "must attend" event if you need to implement the Unicode Standard or manage an internationalization project. IUC 30 has new as well as updated tutorials for the newcomer and expert alike on topics such as .Net, Oracle and Unicode 5.0.
Unicode is the accepted international standard for rendering fonts on computers with different operating systems. Computers with different operating systems are gradually adopting this as the ultimate standard for the future. However, it is still evolving. It is 16 bit standard and is a major step forward compared to other standards for use of fonts on the computers.
Unicode is often referred to as a "super character set." As the Internet becomes more global, it becomes necessary to represent a wider range of languages across Web sites, sometimes representing multiple languages on a Web page. Unicode supports all of the world's major languages. The Unicode Standard has been adopted by most major software vendors and it is supported by both Microsoft Windows and Mac OS X.

The Unicode standard describes how characters are represented by code points. A code point is an integer value, usually denoted in base 16. In the standard, a code point is written using the notation U+12ca to mean the character with value 0x12ca (4810 decimal). The Unicode standard contains a lot of tables listing characters and their corresponding code points:

For all their advantages, Unicode Standards are far from a panacea for internationalization. The code-point positions of Unicode elements do not imply a sort order, and Unicode does not encode font information. It is the operating system that defines these rules, as in the case of Win32-based applications, which need to obtain sorting and font information from the operating system.
