Update character set to Unicode 5.

At the time I wrote this a new version of Unicode (5.0) http://www.unicode.org/versions/Unicode5.0.0/ is out. Some highlights:

    * Additional characters for Cyrillic, Greek, Hebrew, Kannada, Latin, math, phonetic extensions, and symbols

    * New alphabets and scripts, including Balinese, N'Ko, and Phags-pa, and two historical ones, Phoenician, and Sumero-Akkadian cuneiform

    * The inclusion of characters from ISO/IEC 10646:2003 for mathematics and for some Indian and minority languages

    * Changes to the specifications for properties in the Unicode database, including the definition of case-related properties and of bidirectional characters in such languages as Arabic and Hebrew

     * Other changes have to be made for security, as in an earlier version, when multiple renderings of a forward slash in UTF-8 might have permitted crackers to navigate directory structures, or duplicates in different character sets made spoofing of addresses and sites easier. Still another reason is to bring the increasingly small group of languages not covered by Unicode into the standard.

      * Moreover, while all these priorities are being juggled, backward compatibility with earlier versions remains a high priority, although it is not always possible.

It's interesnting to upgrade to Unicode 5.0.
