Hello David -- Thanks for your note. You mentioned: > I note 2 of the 4 that you list: > 2278 > 2279 > are in StandardizedVariants-4.0.0.txt but commented out, and are in the > files I actually used: Right. Just FYI and for future reference: these two characters 2278 and 2279 originally were in our list but then they got removed. This was an action taken by UTC, based on a paper by Mark Davis 2001-03-28, document reference L2/02-126. The decision was based on the fact that 2278 and 2279 are decomposable characters. UTC issued a corrigendum to remove these. There is an explanation of this in Unicode Technical Report #28 (Unicode 3.2). An errata report was filed to the MathML WG on 02 April 2002 by Martin Duerst. > Unless I have missed something the lack of a variant of 2225 introduces > another unfortunate case where Unicode doesn't have enough characters to > support the ISO entity sets in any plausible way, in this case parsl in > ISO 9573 part 13 ISOTECH.

Someone will need to gather the relevant info and propose this. Probably fairly easy to get this rolling. I would suggest that Asmus Freytag is the person to help coordinate this proposal. I'm CCing him on this note... Thanks again. Rick
