[Zope] Quoting quotes

[Charlie Reiman]

I have a little dtml and python and I'd like to call the python with a
string containing a double quote:

<dtml-var expr="pything('she said "Yes."')">

Obviously, this doesn't work. Not so obviously, these don't work either.

<dtml-var expr="pything('''She said "Yes."''')">
<dtml-var expr="pything('She said \"Yes.\"')">

The only solution I've found is the icky:

<dtml-var expr="pything('She said \x22Yes.\x22')">

or

<dtml-var expr="pything('She said \042Yes.\042')">

Is that the only way? Does dtml lack any kind of escape sequence? I can
understand why there wouldn't be one but I'd like to be sure before I go
