[EP-tech] URI::Escape error in URI::_query

URI::_query cannot handle wide characters (including non-ASCII Unicode), throwing up the following error:

Use of uninitialized value within %URI::Escape::escapes in substitution iterator at /usr/local/eprints/perl_lib/URI/_query.pm line 16, <$fh> line 287.

I added a trivial patch to said file, based on the difference between URI::Escape's uri_escape and uri_escape_utf8 methods (see below).  My question is: is it reasonable for the query() method to assume all inputs are octet strings instead of character strings?  And if so: how do we police all entrypoints to ensure data sanity?
