Hi,
With a desire to write elegant/optimal code in perl,i want to know any suggestions the monks might have to spare me.
A customer gave me a word document with country (duplicates due to multiple commitees per country)names.
I need to create a drop down in html showing country names. Hence my trivial code below to read a list of duplicate country names , identify unique names and write them to a file in alphabetical order. Basic stuff. 
#!/usr/bin/perl

use strict;

my ($key,$name,%countries);
open (my $fh1,"<","files/country_listv1.txt") or die $!;
while(<$fh1>){
  if (!exists $countries{$_}){
    $countries{$_} = '1';
  }
}
open (my $fh2,">","files/country_listv2.txt") or die $!;
foreach $key (sort keys %countries){
    print $fh2 $key;
  
} 
close($fh1,$fh2);

update I still have one issue the comma character appears as €TM. I suspect its a encoding issue of my text file. I am using textedit on a mac which doesnt seem to have a save as UTF8 option.strange. Im just updating this query than create a new one. Im going to try some options but please tell me which is the best way out, as this problem seems a generic one. use utf8 encoding in my perl script. recreate the text file in vim any other options ?

Do we have some perl code checker available for us to validate scripts / modules ?
Thanks
