Thanks for indicating the subtle difference.

I've been struggling with this very issue recently and came across a url here at perlmonks that uri_escape doesn't handle, and requires CGI::escape. This small CGI program compares uri_escape and escape by producing two links to perlmonks: 

#!/usr/bin/perl

use CGI qw(:all escape escapeHTML);
use URI::Escape;

$site = 'http://www.perlmonks.org/index.pl?node=';
$user = 'Clive ;-)'; # my test case for whitespace and funny chrs

print header,h1("compare");
print
     '<A HREF="',
     escapeHTML(uri_escape($site.$user)),
     '">',
     escapeHTML($user),
     '</A> - <tt>escapeHTML(uri_escape($site.$user))</tt><br>'; # does
+n't work

print
     '<A HREF="',
     escapeHTML($site.escape($user)),
     '">',
     escapeHTML($user),
     '</A> - <tt>escapeHTML($site.escape($user))</tt><p>'; # works

The 1st print using uri_escape on the whole url returns:
http://www.perlmonks.org/index.pl?node=Clive%20;-)

The 2nd print using CGI::escape on the param only, yields: http://www.perlmonks.org/index.pl?node=Clive%20%3B-%29

As you can see the semicolon is causing a problem in the uri_escape url.
Is this a general condition or just a peculiarity of perlmonks?
