You could run 'grep VERSION /usr/share/perl5/URI.pm' to get the
version number out of the file.  If you have the same version as me
you will find:

  $ perl -ne 'print if 72..76' /usr/share/perl5/URI.pm
  sub _init
  {
      my $class = shift;
      my($str, $scheme) = @_;
      $str =~ s/([^$uric\#])/$URI::Escape::escapes{$1}/go;

so the warning means that perl finds characters in your URI that does
not have corresponding entries in %URI::Escape::escapes.  Hmm, I guess
that can happen if you feed it strings with Unicode chars outside the
Latin 1 range.  Can that be the case?
