Hi vit, this will decode url-encoded characters, however have you considered the CGI module?

use CGI;
[download]

with or without qw/:standard/ or CGI::Pretty if you want to out put formatted HTML
Now param('men\'s_cloth'); returns the associated value or if this is a value, it will be avalable under the appropriate parameter.
BTW, is taint (-t) on? because you should be suspicious of quote characters returned to your script.
