Really?  I've never had occasion to try it ... so I just did. Here is
the Python script -

str = 'c:\this\is\a\test'
return str

When called via dtml-var, each character after a backslash was missing
or otherwised changed.  I had to double the backslashes to get the
string returned correctly.

Cheers,
