problem I stress above, your critics should be addressed
somewhere else, since the Unicode standard is specifically
organized to make this possible and easy, down to variants of

<p>Just a small complement: a function in Python which reads base 10
numbers encoded in Unicode (and fails if given something else,
including mixture of several digits) is as simple as the
following:</p>

Of course, it‘s a quick hack, which probably should be optimized
and also should take special cases into account, notably ᧚<span

face="monospace"><br>
</font></p>
<p>But the point is: Unicode indeed makes the parsing of many
base-10 numerals used for many scripts easy, since the small code
snippet above works for almost 50 scripts. Note that the hardcoded
string <font face="monospace">sdigitszero</font> is simply the
unicode characters of category <font face="monospace">Nd</font>
with <font face="monospace">Decimal_Digit_Value==0</font> and
nothing else.<font face="monospace"><br>
