mandating Unicode collation for Perl?

Hello,

Now that there is always unicode collation for C, I would propose to
have the same requirement for Perl, that is require Unicode::Collate
to be present.  Nowadays, texi2any in pure Perl is a different option,
mainly relevant for users in case of issues with C, I think that it
would be better if the pure Perl option had the same features as the C
command.
