+ * Allowed title characters -- regex character class
+ * Don't change this unless you know what you're doing
+ *
+ * Problematic punctuation:
+ * []{}|# Are needed for link syntax, never enable these
+ * % Enabled by default, minor problems with path to query rewrite rules, see below
+ * + Doesn't work with path to query rewrite rules, corrupted by apache
+ * ? Enabled by default, but doesn't work with path to PATH_INFO rewrites
+ *
+ * All three of these punctuation problems can be avoided by using an alias, instead of a
+ * rewrite rule of either variety.
+ *
+ * The problem with % is that when using a path to query rewrite rule, URLs are
+ * double-unescaped: once by Apache's path conversion code, and again by PHP. So
+ * %253F, for example, becomes "?". Our code does not double-escape to compensate
+ * for this, indeed double escaping would break if the double-escaped title was
+ * passed in the query string rather than the path. This is a minor security issue
+ * because articles can be created such that they are hard to view or edit.
+ *
+ * Theoretically 0x80-0x9F of ISO 8859-1 should be disallowed, but
+ * this breaks interlanguage links
