What I wrote was:

Meaning: Tcl 8.0 added "binary strings", and handled binary data in String
objects.  Tcl 8.1 internationalized those strings to make them store UTF-8,
and introduced ByteArray objects to hold binary data. So the original code
should work fine in Tcl 8.0, and the changes are only needed at 8.1 and up.
I'm guessing, though, so I'll go dust off a copy of Tcl 8.0.x and try it.
