Unicode Explained: Internationalize Documents, Programs, and Web Sites
Purchase options and add-ons
Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. There are hundreds of different encoding systems for mapping characters to numbers, but Unicode promises a single mapping. Unicode enables a single software product or website to be targeted across multiple platforms, languages and countries without re-engineering. It's no wonder that industry giants like Apple, Hewlett-Packard, IBM andMicrosoft have all adopted Unicode.
Containing everything you need to understand Unicode, this comprehensive reference from O'Reilly takes you on a detailed guide through the complex character world. For starters, it explains how to identify and classify characters - whether they're common, uncommon, or exotic. It then shows you how to type them, utilize their properties, and process character data in a robust manner.
The book is broken up into three distinct parts. The first few chapters provide you with a tutorial presentation of Unicode and character data. It gives you a firm grasp of the terminology you need to reference various components, including character sets, fonts and encodings, glyphs and character repertoires.
The middle section offers more detailed information about using Unicode and other character codes. It explains the principles and methods of defining character codes, describes some of the widely used codes, and presents code conversion techniques. It also discusses properties of characters, collation and sorting, line breaking rules and Unicode encodings. The final four chapters cover more advanced material, such as programming to support Unicode.
You simply can't afford to be without the nuggets of valuable information detailed in Unicode Explained.

About the author

I'm an IT generalist and specialist with strong interest in humanities--and humans. This explains why I have focused on character codes, localization, and accessibility.
After M.Sc. degree in mathematics, I worked with IT services, user support, software development, and teaching at Helsinki University of Technology over 25 years and also started writing books. Later, I have worked as an author and consultant, in addition to employment periods at the Finnish Information Society Development Center (IT standardization) and at the Blue1 airline company (multilingual online sales and web site). My books in Finnish deal with programming languages (Fortran, Pascal, C), Unix, web publishing, HTML, CSS, data security, office document design and style, and web typography.
My motto is “Docendo disco, scribendo cogito”—by teaching I learn, by writing I think. I love to get deeper insight and wider understanding by formulating things for others, in a manner that is both understandable and informative, correct, and useful—a real challenge.
I’m an advocate of standardization, but with realism learned the hard way. I always try to promote relevant standards and consensus-based recommendations, but I also try to point out their shortcomings and problems in acceptance and in implementations.
You might find me on various discussion forums on the Internet, but I’m partly an old-timer who loved the good old Usenet, where I frequented in many web-related groups. I’m adapting to the new modes of communication, which are partly much more effective (like moderated e-mail lists and StackOverflow).
