Scripts written in perl may identify characters by their Unicode name (see e.g. http://www.xav.com/perl/lib/Pod/perlre.html). Code may reference characters by names automatically derived from the Unicode standard - if Unicode names change the code will fail to recompile if the names in the Unicode standard change. Unicode stability guarantees have assured the code writers that they do not need to worry about this possibility. Richard.
