HANDS-ON: UNICODE > FIRST THOUGHTS

FIRST THOUGHTS

Unicode is not a language, but it deserves a Hands-On chapter of its own because it is unlike any other character set you’ll use. In fact, in a few years it may be the only character set you use. Unicode has been called the “mother of all character sets” because it includes most, if not all, of the characters in the world’s major languages. Technically speaking, Unicode is both a character set and an encoding, or a “character encoding system,” although most people simply call it a character set. To understand how Unicode works, in this chapter you’ll convert the global gateway—now consisting of all graphics—back into text. As you’ll recall from earlier Hands-On chapters, a web page can specify only one character encoding, yet the global gateway includes characters from several different, and conflicting, character encodings. This dilemma forced you to embed the global gateway within graphics. With Unicode, however, you can specify one encoding and still include the world’s many characters on one web page.
