Yep, needless to say, that fixed it. rule-4: pattern-rule { !"#$%&'()*+,-./0123456789:;<=>? @AaᡱBbCcDdEeFf GgHhIiJjKkLl奵MmNnOoPp QqRrSsTtUuVvWwXxYy ZzZz[\]^_`{|}~} 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... --Scott Jones
