huh??, what is this, i'm not aware of anything resembling this being in
zope's core, i think you are using some type of custom lib. if not i'd
like to hear about it?

the html_quote of dtml-var is done on rendering so you really can't
capture the variable in a transformed state. 

the solution is to roll your own pythonmethod. here's one to the trick.


html_encode ttw python method
PARAMETERS: text

BODY
string = _.string

character_entities={"'&'":"&amp;","<":"&lt;",
                    "'>'":"&gt;","\213": '&lt;',                    
                   
"\233":'&gt;','"':"&quot;"}                                              
text=str(text)
for re,name in character_entities.items():
    if string.find(text, re) >= 0:
text=string.join(string.split(text,re),name)
return text
/END BODY


so for your example you would do

<dtml-call "REQUEST.set('htmldesc', html_encode(description))">

qualifying description if you need to.


cheers
