Is there a difference between converting a string of ASCII digits to an integer versus a string of non-ASCII digits to an integer?

It happened for N’Ko anyway:
“N’Ko uses decimal digits specific to the script. These digits have
strong right-to-left directionality. Numbers are stored in text in
logical order with most significant digit first; when displayed,
numerals are then laid out in right-to-left order, with the most
significant digit at the rightmost side, as illustrated for the numeral
144 in Figure 19-3. This situation differs from how numerals are handled
in Hebrew and Arabic, where numerals are laid out in left-to-right
order, even though the overall text direction is right to left.”
