I want to put Tom Hasting's latest proposal aside for a
moment and describe a problem that I realized yesterday was
in the current definition of the Printer MIB. In HP's
implementation of the Printer MIB according to Bob, they
use 8 bit symbol sets in some of their read only objects
depending on localization. In Lexmark's implementation
of the Printer MIB, we use the PC 850 symbol set (which is
an 8 bit symbol set) for all read only objects. HP may use
PC 850 for their read only objects as well, I do not know
but I think that is exactly the problem, there is no way to
know which symbol set is being used for the read only objects
not already covered by a localization object. This has never
been seen as a customer problem up to now because I can imagine
that all printers so far have used only US ASCII (lower code
points) for most if not all read only objects. Most symbol sets
do not vary in the lower code points but vary considerably in
the upper code points. This means that everything works correctly
until some printer implementation decides to use a code point
in the upper portion of a symbol set for a read only object
then all bets are off.

Once I got over the shock when I saw Tom's latest proposal
(Initially I said OH NO NOT ANOTHER LOCALIZATION PROPOSAL!!!!),
I realized that it might be useful in solving the problem
I described above. As a working group, we can say that there
are known problems in the localization area and move forward
without fixing these problems (which to me is an acceptable
way to go. There are always going to be known problems. I
would like to meet the person who says they shipped a perfect
product with no known problems.) or we can stop and try
the fix the problems that we see.
