For these tasks, you should use URI::Escape in libwww-perl-5. Not only
do the authors know what needs to be escaped, they provide you with
simple to use routines so you don't have to know.  (Of course, if you
want to know what and how, you can always look inside.)  Mac ready
versions of libwww-perl-5 are available on my Web site,
<http://mors.gsfc.nasa.gov/>.

The other worry is that the ISO-whatever character set that's the
defined standard for HTML is not the same as the standard Mac character
set, so unless you're using an ISO font, you may have to translate
depending on your application.
