Folks,

I have a large collection of text files which all should be in UTF-8, but some of them are not. I need to determine which ones those are. I am currently trying something like this: 

eval {
   open my $file, '<:utf8', $filename or die $!;
   local $/;
   <$file>;
};
die "$filename is invalid utf8: $@\n" if $@;

If I pass $filename as a file that is not in UTF-8 (i.e. it's in cp1252 which is my other contender) I get a warning on STDERR but the eval does not die as I would like it to. I would like to know, how can I make it do that?
