DirifyES merges both dirify-unicode and dirify-plus. The purpose for dirifyES is to solve a bug in Dirifyplus with unicode languages. Of course, dirifyunicode gives you unicode support. But the main problem with dirify-unicode is that features are worse than those of dirifyplus operator, other than high unicode replacement. In fact, it has just the power of the old dirify operator. DirifyES is aimed at archive mapping with fully human readable URLs.
