in thread Problems w/ encoding in terminal

What would you advice me to correctly output a file content from the same my script? - Again, the file content is in UTF8, but in UTF8 terminal it is not readable since outputed from my script. Do i have to decode the file content every time i want to output it using 'Encode' module?

    Just tell Perl what encoding the file uses. There are several ways:

    When opening the file

    open my $OUT, '>:utf8', $filename or die $!;

    Or, after opening the file:

    open my $OUT, '>', $filename or die $!; binmode $OUT, ':utf8';

    Or, if you want all your output be in UTF-8:

    use open OUT => ':utf8';

    See open, open, binmode for details. You can also use ':encoding(UTF-8)' instead of ':utf8' to let Perl check the validity of the data.

      Awesome! Thank you exceedingly much!

      Thank you very much! It worked.

      Now i have investigated a bit farther on the web and found there is a module

      use utf8::all;

      seems very interesting to me.

      But i got a problem since i have included it:

      utf8 "\xB4" does not map to Unicode (pointing to line 8, please read farther)

      on running my script1, where i set:

      use utf8::all; require 'script2';

      In the script2 i have:

      1 # again 2 use utf8::all; 3 4 sub openfile{ 5 my $file=shift @_; 6 my $cont; 7 open my $fh, '<', $file || die "sopen: Cann't open $file $!"; 8 do{ 9 $cont.=<$fh>; 10 }until( eof( $fh ) ); 11 close $fh; 12 return $cont; 13}

      So, why is it so?

        Without seeing the contents of the file, I cannot tell, but it seems it contains some bytes that are not UTF-8.
