I was wondering, since luatex defaults to utf-8 every where, why the
built-in non-unicode compliant string library isn't overridden by the
unicode library? So instead of having to libraries, make the standard
one unicode compliant and get ride of the separate unicode library. This
would decrease the confusion that is made right now and avoid bugs
caused by code not aware of this important fact? Have this ever been
considered, may be there are technical difficulties?
