- ABSOLUTELY! And it's not just foriegn language concerns, either.
- Modern computing platforms use the entire 8-bit range to represent
- characters. Two of the most common on Mac and Amiga are the
- registered trademark & copyright characters.
-
- It is hard to believe that in 1992, there are still those who think
- that $80-FF is available to do with as they will.
-
- And if we talk foriegn character sets, be aware that some standards
- require TWO bytes to represent one visible character! It would be
- good for the Forth community to start considering these things.

- As far as I know, the only reason this limitation was in effect
- was to facilitate TRAVERSE. The count byte and the last character
- had their top bits set.
-
- This is not satisfactory, as the rest of the world has determined
- there are more valid uses for that bit.
