Hi Monks,

I'm writing Perl lines using the MP3::Tag module in order to verify/modify some tags. I'm kinda new to Perl but I got a lot of things I wanted to work like reading tags, etc. I'm using ID3V2 tags.

Now, I want to write the "TPE2" frame (album artist) and I get this weird problem: every other filled tag of my file loses the last character. Ex: The artist tag set to "Rush" would become "Rus", "1981" becomes "198", etc. but the frame I write in is OK !

Here's my code, sorry if it's not very elegant and loaded with prints... I'm trying to make it work first. It might be useful (or not) for you to know that I want to use this frame as the band's country. I would basically insert an 3-letter ISO country code like USA or GER in the frame.

As you can see, first argument is the filename and second is my 3-letter ISO country code. 
sub setCountry {

    my $myMP3 = $_[0];    
    my $myCountry = $_[1];
    my $objMP3 = MP3::Tag->new($myMP3);
    $objMP3->get_tags();

    if (exists $objMP3->{ID3v2})
    {
    
        my $objMP3ID3v2 = $objMP3->{ID3v2};
        my ($tmpStrAlbumArtist, $tmpStrLong) = $objMP3ID3v2->get_frame
+("TPE2");
        
        if (defined $tmpStrAlbumArtist)
        {
            if ($tmpStrAlbumArtist eq $myCountry)
            {
                print "was already $tmpStrAlbumArtist ... no update\n"
+;
            }
            else
            { 
                print "Tag exists but is different than expected = $tm
+pStrAlbumArtist  ...  no update\n";
            }
        }
        else
        {
            $objMP3ID3v2->add_frame("TPE2", $myCountry);
            my $result = $objMP3ID3v2->write_tag();
            
            if ($result == 1)
            {
                print "Updated successfully to $tmpStrAlbumArtist ...\
+n";
            }
            else
            {
                print "Error while updating ...\n";
            }
        }
    }
    else
    {
        print "No existing ID3V2 tag ...\n";
    }
    
    $objMP3->close();
}
