Thanks very much, Petko.  For my purposes (dynamically creating urls
for social bookmarking links) what I really needed was, as you just
suggested, something like

Markup('urlencodetext', '>textvar:',"/\\(:urlencode
(.*?):\\)/ie","UrlEncodeText(\$pagename, PSS('$1'))");
function UrlEncodeText($pagename, $what){return urlencode($what);}

because then I can do the following to have, for example, a link to
post to del.icio.us:

[[http://del.icio.us/post?url=(:urlencode
{*$PageUrl}:)&title=(:urlencode {*$WikiTitle}:)+:+(:urlencode
{*$Titlespaced}:) | Attach:Site/delicious.png"Save to del.icio.us"]]

and in a pagelist, (:urlencode {=$Titlespaced}:), etc.
