[Fontconfig] Available glyphs?

I *think* I need to interpret the matrix returned by

 fc-query -i index GFSBodoni.otf
which is of the form

0001: ffffffff feffffff ffffffff ffffffff 00040000 00818003 00000000 fc300000

Guessing this translates to a point by prefixing the column 1 last eight bits
with the column n bits... E.g. for the above (second row)

1 1111  1111 1111 1111 1111 1111 1111 1111

So where there is a 1, the glyph at code point x is present,
    where there is a 0, the glyph is not present.

Yet to find confirmatory documentation for this?

If ea row has 32 * 8 = 256 chars per line?
I can interpret that as presenting 64K chars per font?

Is my logic sound please?

I think I can work out something to translate that.
