It was not a slip-up. It was deliberate at the time (1993). Note that as of 1993, the only "LAMDA" or "LAMBDA" characters in the standard were: 039B;GREEK CAPITAL LETTER LAMDA;Lu;0;L;;;;;N;GREEK CAPITAL LETTER LAMBDA;;;03BB; 03BB;GREEK SMALL LETTER LAMDA;Ll;0;L;;;;;N;GREEK SMALL LETTER LAMBDA;;039B;;039B 019B;LATIN SMALL LETTER LAMBDA WITH STROKE;Ll;0;L;;;;;N;LATIN SMALL LETTER BARRED LAMBDA;;;; Also note that all 3 of those data entries from UnicodeData.txt have explicit Unicode 1.0 data fields, showing different names for Unicode 1.0. All *other* "LAMDA" characters were added considerably later, and their choices for spelling were influenced by the then standardized spelling for 039B/03BB, and by preferences expressed by various national body during balloting. Note that: 1038D;UGARITIC LETTER LAMDA;Lo;0;L;;;;;N;;;;; is a distinct issue, and would no doubt would still have been spelled "LAMDA", even if all the Greek characters in the standard had been spelled "LAMBDA". --Ken
