Dear monks

I have to import text files into a SQLite database. Text files are generally provided in UTF-8 encodings. However, I cannot exclude that a file can be in another format. I would like to check if my text file is in UTF-8, if not discard it (printing an error message). I have this script. But something seems not to work. I'm now trying to check every line, even if it could be -maybe- better to check the file as a whole

#!/usr/bin/perl
use warnings;
use strict;
use Encode;
use Encode::Guess;

open (DATA, "<:utf8", "a.txt") or die $!;
binmode DATA, ":utf8";
my $line = <DATA>;

while($line){
    my $decoder = guess_encoding($line);
    if (ref($decoder) eq 'Encode::utf8'){
    print "File is in UTF-8\n";
        #doing something
    }
$line = <DATA>;
}
__END__
