: What say you?
The intent was that \d match all decimal digits (Nd), but not other
numbers (No), such as superscripts. Basically, can you do a tr///
on \d+ and feed it to atoi() meaningfully?
See section 4.6 in the Unicode Standard 2.0 for more details. I don't
know if this has been modified for 3.0.
