[Fontconfig] fc-query output, misunderstanding?

[Dave Pawson]

I'm returning to this thread since my understanding of this is somehow wrong.

The output from fc-query in question is
00e0: 00000000 00000000 00000070 00000800

I'm translating from the matrix to Unicode code points.

If I understand it correctly, the starting value of each group in this line is:

E000  E020  E040 ...
Hence for the group 00000070
                                1           32
The characters are in the range E040..E5F

Which 'end' of the group represents the lower value please?
The left hand or right hand end?
Is E040 bit 1 or bit 32?

Is this documented anywhere please?

TIA
