Hi Herb,
Just curious... what happens when you try to do search within or a
copy from a pdf which has such combined characters?
PDF has the /ActualText(...) replacement tagging feature. This allows
you to capture a sequence of content characters
and declare the whole collection to be equivalent to a single (or
sequence of) Unicode point(s).
But, that only works if you add an /ActualText command. As far as I can
tell, using a compound glyph as discussed here will not be a problem in
a search, *provided* that the software you're using implemented the
unicode collation algorithm correctly, in which case for this type of
thing it shouldn't need the /ActualText command for searching to work.
That said, I have no idea how many PDF readers other than Adobe's
Acrobat actually use a correctly and fully implemented unicode collation
algorithm.
