Here si the code that procudes and fills the contents of the drop down menu:
my @files = <../data/text/*.txt>;
my @display_files = map /([^\/]+)\.txt/, @files;
print br;
print start_form( action=>'index.pl' );
print h1( {class=>'lime'}, "Επέλεξ&#
+949; το κείμενο π&#
+959;υ σε ενδιαφέ	
+61;ει => ",
popup_menu( -name=>'select', -values=>
+\@display_files ),
submit('Εμφάν
+ιση'));
As Ani from efnet told me maybe the OS i use (xp from MicroSuck) is so damn persisting on creating utf-8 file contents buu saving the filenames as iso-8859-7 instead!!!
What do you think folks?
