Hi,
Casing context Final_Sigma is being used in SpecialCasing.txt, but its
specification is no longer present in the standard (at least I can't
find it). Obviously this context is now called Final_Cased, but the
specification for Final_Cased (section 3.13) is not identical to that
of Final_Sigma (UAX 21, superseded).
regexp Final_Cased:
Before C [{cased=true}][{wordBoundary!=true}]*
After C !([{wordBoundary!=true}]*[{cased=true}])
regexp Final_Sigma:
Before C <cased> <case-ignorable>*
After C !(<case-ignorable>* <cased>)
Is the old specification of Final_Sigma still valid for determining
the final sigma casing context, or are there situations where it
is inadequate? What I mean is are these specification actually
the same WRT final sigma?
