Unicode objects should have a pointer to a cached (read-only) char
buffer <defencbuf> holding the object's value using the current

parsing (see below) reasons. The buffer is filled when the first
conversion request to the <default encoding> is issued on the object.
keeping track of an external encoding is better left
for the application programmers -- I'm pretty sure that
different application builders will want to handle this
in radically different ways, depending on their environ-
ment, underlying user interface toolkit, etc.
besides, this is how Tcl would have done it. Python's
not Tcl, and I think you need *very* good arguments
for moving in that direction.
