Is Missing( " " ) returns True?

[#1]

I would like to differentiate a space cell and an empty cell.  The Is Missing() function interprets both as missing.  Is there a better way?

I am using JMP 16.2.0.

New Table( "Example",
	Add Rows( 1 ),
	New Column( "Empty", Character, "Nominal", Set Values( {""} ) ),
	New Column( "Empty Missing?",
		Numeric,
		"Continuous",
		Format( "Best", 12 ),
		Formula( Is Missing( :Empty ) )
	),
	New Column( "Space", Character, "Nominal", Set Values( {" "} ) ),
	New Column( "Space Missing?",
		Numeric,
		"Continuous",
		Format( "Best", 12 ),
		Formula( Is Missing( :Space ) )
	)
)

A blank is just "" and it seems like JMP trims the inputs of spaces to just be blank again.  

Names default to here(1);
dt = New Table( "Example",
	New Column( "Fun", Character, Set Values( {" ", "", "A"} ) ),
	New Column("State", character,  Formula(
		Match(:Fun, 
			"", "Blank", 
			" ", "Space"
		, // else
			"Filled"
		)
	))
);

dt:Fun << Get Values(); // {"", "", "A"}

At least in 16.2

I know in earlier versions you couldn't even do ismissing() on non numbers.

To add to @vince_faller , JMP does convert " " to "" in inputting into a data table, however, it does not conver " a" to "a".  That is, when valid characters do exist in the given cell, JMP maintains the leading spaces( "20" hex).  JMP also has escape strings to input blanks( \!b )( "08" hex ), and nulls( \!0 )( "" hex ).

Thanks @vince_faller and @txnelson .  This is not the answer I was hoping for, but it does explain the behavior.
