Getting the HTML and URI escaping right for creating links and labels is fun, not! But if you've got the right template to start from, it's not so bad. Here's a basic snippet. Handles whitespace correctly, as well as %, &, <, and >. Beware hand-rolled solutions which don't.
#!/usr/bin/perl
use CGI qw(:all);
use URI::Escape;

print header, start_html("sample"), h1("sample");
print map { a({ -href => uri_escape($_)}, escapeHTML($_)), br } glob "
+*";
print end_html;

Note that the HTML a shortcut does an escapeHTML on the HREF attribute automatically. The manual equivalent would be: 
print
  '<A HREF="',
  escapeHTML(uri_escape($_)),
  '">',
  escapeHTML($_),
  '</A>';

Yes, all that escaping is necessary. Do not shirk.
