That is what I exspected. Thank you for verifying that for me.

Yes, I noticed, that this file is informational. But it is very useful to
have:-) From what I read about it I guessed that it was completly derivable
from the other, normative, data. So these deltas were a surprise for me.
Thank you for pointing out this misconception.
A sidenote: The standard is a great book to have when you need to work with
characters as it points out many pitfalls that are not obvious to the latin-1
using programmer. It is well written and easy to understand. The only
problem I encounter from time to time is figuring out which characters you
mean exactly when you talk about groups of characters. Maybe it is possible
to define Properties for all those groups in the next version of the
standard? This information is redundant, but it would help me greatly.
