	// Search & replace patterns and variables for matching (and conversion of) ISO-8859-1 character case & classes.
	// Search & replace patterns must be specified as perl-style regular expression and search patterns must include the
	// leading & trailing slashes.

	// NOTE: Quote from <http://www.onphp5.com/article/22> ("i18n with PHP5: Pitfalls"):
	//       "PCRE and other regular expression extensions are not locale-aware. This most notably influences the \w class
	//        that is unable to work for Cyrillic letters. There could be a workaround for this if some preprocessor for the
	//        regex string could replace \w and friends with character range prior to calling PCRE functions."

	//       The 'start_session()' function in file 'include.inc.php' should establish an appropriate locale via function
	//       'setSystemLocale()' so that e.g. '[[:upper:]]' would also match 'Ø' etc. However, since locale support depends
	//       on the individual server & system, we keep the workaround which literally specifies higher ASCII chars of the
	//       latin1 character set below. (in order to have this work, the character encoding of 'search.php' must be set to
	//       'Western (Iso Latin 1)' aka 'ISO-8859-1'!)
	//       higher ASCII chars upper case = "ÄÅÁÀÂÃÇÉÈÊËÑÖØÓÒÔÕÜÚÙÛÍÌÎÏÆ"
	//       higher ASCII chars lower case = "äåáàâãçéèêëñöøóòôõüúùûíìîïæÿß"

	//       The variables '$alnum', '$alpha', '$cntrl', '$dash', '$digit', '$graph', '$lower', '$print', '$punct', '$space',
	//       '$upper', '$word' must be used within a perl-style regex character class.
