This generates characters from decimal 8300 - 8400 (because that range
includes raised and lowered digits which have the number and value
properties equivalent to 0-9.

----

No? 8300, 8400 arbitrary code points that contain raised and lowered numbers
that have the number property (as does 0..9):

perl -we' use strict; use v5.16;
my $c;
for ($c=8300;$c<8400;++$c) {
my $o=chr $c;
printf "%s", $o if $o=~/\pN/;   #match unicode property "is_num"
};printf "\n"'
⁰⁴⁵⁶⁷⁸⁹₀₁₂₃₄₅₆₇₈₉

Q.E.D.


Is that sufficient proof?
