Hmm.  Someone added code in 7.2 to support conversion between the
database's encoding (whatever you specified with -E) and the UTF-8
encoding that Tcl wants to use all the time.  Sounds like you've
found a bug in that code.

Do you see it *only* in references to NEW/OLD?  Can you pass the
same data in normal parameters to a Tcl function?
