I receive files with human names in ALL CAPS, including accented upper case characters. The files are in iso-8859-1. 

CLÉ USB
CLÉMMY USB

I need to "proper-case" these words, i.e., Initial Cap All Other Characters Lower Case.

When I open these files in vi, I don't see the upper-case accented E; I see a question-mark. 

CL? USB
CL?MMY USB

But when I run these lines through Encode::from_to, I do get the upper case accented E. But no matter what I do, I can't seem to lower-case that upper-case accented E. In fact, the succeeding character remains upper-case as well. 
use strict;
use warnings;
use feature qw( :5.10 );
use Data::Dumper;$Data::Dumper::Indent=1;
use Carp;
use Encode qw( from_to );
use POSIX qw( setlocale LC_CTYPE );

setlocale(LC_CTYPE, "fr_CA.ISO8859-1");

my $file = q{./yard};
open my $IN, '<', $file or croak;
while (my $l = <$IN>) {
  chomp $l;
  say "1: $l";
  my $m = $l;
  from_to($m, "iso-8859-1", "utf8");
  say "2: $m";
  say "3: ", xlc($m);
}
close $IN or croak;

sub xlc {
    my $str = shift;
    return join q{} => ( map { ucfirst(lc($_)) } ( $str =~ m/(\W+|\w+)
+/g ) );
};

What am I doing wrong?

Thank you very much.
