SPUG: Stupid Ascii question

[Peter Darley]

Friends,
	I am working with database stuff and I want to store deleted database
records, so there's a history of what was in the database.  I have chosen to
do this by having my front end app, written in Perl, put all the field names
and values into a single string separated by a non-printing Ascii character
which I can just do a split() on later to return a hash of the record, which
is exactly what I would get if I did a fetchrow_hashref() on the original
record.
	My question is this; what non-printing Ascii character can I use for this?
I wanted to use chr(0), the ascii null, but postgresql or DBD::Pg or DBI or
something chokes on it.  I went with chr(31) which is described as 'unit
separator'.  I'm worried that there may be some unexpected interaction with
file systems or something that I'm unaware of, so I thought I'd ask y'all.
Thanks,
Peter Darley
