Right, so to get this in we either need to decide that we're OK with
adding that many characters, or figure out some systematic way to
select just the ones we want. One hint that might be helpful if
someone wants to investigate: I suspect that a lot of those mappings
might be marked with <font>, which seems to be for code points for
alternative renderings ("mathematical" bold, italic, fraktur etc), so
perhaps we could filter them out that way without losing the
oxia-marked characters if that's the way it has to be.
I think all the relevant part of the character database file is described here:
https://unicode.org/reports/tr44/#Property_Values
The file we're currently using is 15.1:
