Simon,

Thanks for this.  I *think* the (obvious when you think about it) thing
I've learned today is that ruby uses inspect when generating error
messages: I headed off down this blind alley when I got an error
something like:

t.rb:1:in `open': No such file or directory - "J:\\dir\\subdir\\"
(Errno::ENOENT)
        from t.rb:1:in `entries'
        from t.rb:1

.. and I assumed that "J:\\dir\\subdir\\" was what ruby was 'seeing'.
I must look elsewhere for the true cause of my bug.
All the best,
Jon

You're being bitten by the fact that p uses inspect, and
String.inspect gives you a "displayable" representation of a string
that can be re-evalled back into ruby. 

"\\" does what you want: 

 %  ruby -e 'print "\\"'
