Over the years, there has been much discussion about those codes with
numeric values from 128 to 255.  I agree with you that they are not part
of ASCII, but have often been called the Extended ASCII characters or
high ASCII.  In times gone by, they were even often prohibited in
messages in many echos.  For what it is worth (not much), EchoPol1
section 18 refers to them and says that they are prohibited (but in the
next breath allows them).

 RN> I don't recall who got us on this tangent, but I do know it was not
 RN> me.  I was simply answering Robert Bashe's question.

 MVDV> In a follow up you accused me of using wrong arithmetic 
 MVDV> when I wrote it appeared that Max strips the high bit.

Which was a nonsensical remark on his part in response to an accurate
statement on your part.
 
 MVDV> That may be so, but that does not make my arithmetic invalid.

True -- the ones who said it was invalid did so because they not
understand what you were saying and went off (in mass) on another
direction.  What you said was clear to me, and needed no comment from
anyone.

 MVDV> The superscript 2 is character number 253 in DOS code pages 
 MVDV> 437 and 850. If you strip the highest bit (same as 
 MVDV> substractting 128), you get character number 125. Which 
 MVDV> happen to be '}'.

 MVDV> Nothing wrong with my arithmetic.

True, nor was there anything wrong with *your* statements.
