Thanks. This helps a good deal. I'm mystified as to why 166 (aka 'Broken
bar') is displayed as a minute formless squiggle and 214 is displayed as a
broken bar but I can survive without that knowledge

Yes. It performs an unwanted one :-). It looks like a problem between Java
and the DOS commandline. What particularly worried me was that simple Java
code using 'char' translated this character into 65446, which presumably
has a completely different meaning in Unicode. IOW there is a danger that
corruptions could take place.
