Yep, needless to say, that fixed it.

Here is the rule pattern I **generated** from my table for the ISO-8859-2
character set. Currently, this is sorted big-uns before little-uns. If the
character looks totally out of place, it is because this representation used
the ISO-8859-1 implicit in REBOL. Which brings me to the next "problem",
there will be no way to generate the proper character that isn't already
contained in the standard character set. So some sorted solutions will not
appear
to be correct, until the result is displayed in the correct
character representation set. This does not appear to be a problem in
Hungarian (so far), but will be in other languages. Hmmm.....
Keep up the good work. I look forward to seeing your ideas regarding the
multi-letter graphemes
in the separate post (which has not yet arrived
here ... whoops .. just arrived!).
Later...
