I had a similar problem that I needed to deal with quote characters in some
form data that was being handled in javascript.  I added a new quoting
format to dtml-var.  I changed DT_Var.py in Lib\Python\DocumentTemplate to
add the following function:

def jscript_quote(v, name='(Unknown name)', md={}):
    v=str(v)
    if find(v,"\\") >= 0: v=join(split(v,"\\"),"\\\\")
    if find(v,"'") >= 0: v=join(split(v,"'"),"\\'")
    if find(v,'"') >= 0: v=join(split(v,'"'),'\\"')
    if find(v,"\t") >= 0: v=join(split(v,"\t"),"\\t")
    if find(v,"\n") >= 0: v=join(split(v,"\n"),"\\n")
    if find(v,"\r") >= 0: v=join(split(v,"\r"),"\\r")
    return v

Probably not the most efficient way to do it, but it works.  You also need
to add a reference to it in the "args=parse_params.." line, and to
"modifiers".

You could always just extend this to do the encoding of non-displayable
characters as well.  Look at the code for url_encode.

It would be nice if there was a product for this, but that's a bit beyond my
experience at present.
