Digit!
(perl from Macports and perl from /usr/bin/perl behave the same in this respect.)

- pfedor 13y agoGood to know, thanks. I'd argue that perl gets it right--as the default behavior, this behavior would gravely violate the principle of least surprise, but for the 0.01% of people who want \d to match ੧, there's no harm to making it available as an option you need to specifically request.
