The @t{} trick was to avoid converting ' into ’, which is definitely
not how this word should be displayed.  So I think the @iftex part of
your proposal needs to use @t{'}.

Is that official?  Can you tell where you saw that this is the
preferred spelling?  We should be very careful with such situations,
as people tend to get offended when their names or the names of their
nation or religion or language is misspelled.

Thanks.
