	Ok, I am feeling a little picked on here... a lot of people like
using uEMACS for pointing things like this out.  When I first started
working with it, it was just for me. But that is really no excuse...

	And someone finally proposes some solutions rather than just
blindly stabbing out and complaining.  The last round of complaints I
sent out a request for information on this problem, and the best I got
back was.. go to the library and do some research.  Well for a project I
am doing in my spare time, considering the poor library system round
here I really wasn't happy to here all the griping and then get no help
from anyone to fix the problems.  So I applaud Mr. Gudmundsson for his
mail.

	However, after the last round, I thaought carefully about the 8
bit problems, and resolved that the issue was too complex on a language
by language basic for me to ever attempt to get all the case mappings
correct.  So when you see the next version of MicroEMACS, it will have
a user changable upper/lowercase mapping function (which is working
right now).  Note: This slows down the regular pattern matching code
considerable, so uEMACS can be compiled with the diacritical (un
american in this case) turned off, but both options now exits.
