I couldn't find this information in the archive...

I like the ESCAPE options (HTML, URL, JS).

Is there a way to also escape whitespace?  In particular, I would like
an easier way to replace spaces with  

Currently looping through data from dbi and replacing.  Any ideas?
    

Don't do that?    really shouldn't be needed in modern HTML
layout.  Maybe you can show us what you're using it for and we can
suggest a better way?
  
Hi Sam,

One of the mods that I made to my local copy of H::T was to allow the ESCAPE modules to be dynamically loadable so that users could implement escaping according to whatever rules they had.

Would you be interested in a patch to allow this feature?
