Collation tables can aleady be tailored very easily with existing technologies. And anyway this has nothing to do with directionality of characters, or their rendering, on which they absolutely do not depend. Tailored collations already have a working standard and syntax in the CLDR project or ICU and in a few other libraries (notably in CPAN for Perl).
