Thanks Seth, I would certainly like to have UNICODE support, so perhaps the AXE libraries would be a proper solution :) I just need to see if it will work with the MSVC10 compiler, then it will be the solution I am looking for :) The other option is to use something such as iswdigit with the unicode string library: ICU There's a lot more to consider, but it seems like the boost libraries aren't what I require for this project... so I will keep discussion off of these mailing-lists in future. Thanks all for your solutions, Alec Taylor On Sun, Nov 13, 2011 at 3:37 AM, Seth Heeren <bugs@sehe.nl> wrote:

I am thinking to piece this together using just the stdlib (std::isdigit &etc)... what do you think?

By all means. My money is on the hybrid regex+stdlib approach.

I haven't had the time to evaluate the Axe Library suggested on SO. On first sight it looked like a regex+native hybrid but with nicer library support.

But if you have a plan of attack, just go for it. Please, keep in mind that this is the Boost Spirit general mailing list, and therefore not really suited for continued discussion in other directions :)

Cheers, Seth
