I'm not quite sure I follow you here, Christian ; 089c is the hexadecimal
representation of the number represented by the decimal 2204

Yes, but the 2204 is not a decimal number. 2204 is already a
hexadecimal representation.

[...] so I don't understand where the «double conversion» comes in.

Your converting a "number" to hexadecimal that is already hexadecimal.
It is not two thousand two hundred and four, but 2*16³+2*16²+4 = 8708

As I understand it, 2204 is the decimal and 089c the hexadecimal
code for the glyph «∄»,

No. 2204 is the hexadecimal representation, and 089c is a completely
different character (one that is not assigned)

and the first page of Table de caractères Unicode ( would seem to back me up.

No, on the contrary, when you look up 089c there (go to 0890 in the
leftmost row, then go to the c = 12th column (starting to count with
0, i.e. the columns with characters are
0890, 0891, … 0899, 089A, 089B, 089C (=2204), 089D, 089E, 089F

Nowhere in the table's body, you'll see a hex digit, none of the small
numbers above the characters contains an a, b, c, d, e or f, while the
"outer" numbering does - thus those little number cannot be
hexadecimal, but those are the decimal ones, they are increased by one
left to right, top to bottom.

go to locate the 2200 in the
leftmost index column, go to the 4th (again starting with 0) column
and you are at "our" character U+2204, with decimal number 8708.

But perhaps this
is a misunderstanding on my part, and if so, I should be grateful if you
would disabuse me....

Hope that helps.


Thanks, Christian ; I stand corrected....
