I tried the below code for decoding but still got empty lines.

Some unexpected empty lines or only empty lines?

Empty lines after (almost) all lines you read? chomp!

#!/usr/bin/perl
my $input=$ARGV[0];

Add use strict; and use warnings;. Ignoring perl's debugging aids just wastes everyone's time.

And finally, whenever you think that perl has encoding problems, show us a hex dump of the input and the output.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
