FYI:   A few years ago, I had “unexplained problems” with Storable, in which it successfully stored nearly all, but not all, of my records.   I therefore quickly switched to JSON, and during the course of the project found it quite advantageous to be able to easily look at what a particular record contained.   This was a number of years ago, so it might have been fixed now, and in any case I never did piece together what the bug in Storable might have been.   (Nothing to do with Unicode or any of the other “usual suspects ...”   It just stored it but then couldn’t retrieve what it had stored.   I haven’t used the module since.)
