in thread NCR & CER to UTF-8

1) When you use perl with data that isn't ASCII, it's generally a good idea to tell perl what encoding you expect the filehandles to use, by using binmode: binmode(\*STDOUT, ':utf8');. By default, even in utf8 locales, STDIN, STDOUT, and STDERR are assumed to be latin-1. If you had a use warnings, you would have gotten a lot of warnings about a wide character in print -- one for every character that wasn't in latin-1.

2) From that screenshot, it appears that what you have is mostly valid utf8, but the thing you are using to view it expects it to be latin-1, not utf8.

3) It's dangerous to HTML-unescape text containing unescaped HTML or XML tags; after doing so it is impossible to tell the difference between what was <foo> and &lt;foo&gt;, making tags out of things that were not tags before.

4) Why aren't you using a HTML parser, such as HTML::TreeBuilder?

    Hi theorbtwo,

    Thank you so much for your quick reply.

    1) By using binmode, I got correct UTF-8 output now.

    2),3) & 4) You are absolutely right. I need learn more and more about Perl :)

    Thank you for all help.
