This script configures PmWiki to use utf-8 in page content and
pagenames. There are some unfortunate side effects about PHP's
utf-8 implementation, however. First, since PHP doesn't have a
way to do pattern matching on upper/lowercase UTF-8 characters,
WikiWords are limited to the ASCII-7 set, and all links to page
names with UTF-8 characters have to be in double brackets.
Second, we have to assume that all non-ASCII characters are valid
in pagenames, since there's no way to determine which UTF-8
characters are "letters" and which are punctuation.
