It doesn't work for me.  Looks like I'll maybe have to avoid \n altogether,
use spaces to separate the strings and read characters individually.
Basically I have a few hundred thousand sets of 4 tables, each associated
with a unique key.  The idea was to store them as a text file so that I
could quickly fire them into a dictionary (memory permitting?) when I need
to use them.  Maybe I should be using MySQL for persistence?  What I *would*
like is a reasonably generic (and not terribly inefficient) solution for
storing strings that contain escape characters in text files.  Cheers.
