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

[Markus Scherer]

I suspect that Roger is just looking at decimal digits (property gc=Nd
<https://util.unicode.org/UnicodeJsps/list-unicodeset.jsp?a=%5B%3Agc%3DNd%3A%5D%26%5B%3Anv%3D4%3A%5D&g=bc&i=>
).
I believe that they can all be parsed like strings of ASCII digits (and you
can call ICU or other libraries to get at the digit values and other
properties).
I suggest you double-check about the RTL digits (N'Ko & Adlam); please take
a look at the relevant Unicode book chapters.

What's more interesting is handling the grouping and decimal separators
which differ by both language and region.
