A grapheme of a given script is a unit which a graphemosystematically
naive user of the script is disposed to point at and say without
hedging "This is a basic unit of the script."

I grant that this definition is only subjectively objective, but
I believe it to be useful. It is rather analogous to the use of "word",
unqualified, in ordinary linguistics.
