Hi, I have a portability problem with regex (probably due to localization issues).
I've found that, under Win32, the regular expression "\w" matches all the alphanumeric chars, including non ascii ones (such as e grave or e acute). This doesn't hold while under linux. In fact, \w only seems to match ascii characters. I've tried chancing the locale, but nothing changed. Is there a way to make \w have on linux the same behaviour it has on win32?
Sure, it all comes down to what the default C++ locale is: std::locale::global(std::locale("en_US")); called before any regexes are constructed would set the locale to "en_US" *provided that locale is supported by your implementation*. Alternatively, you can set the locale in specific regex instances: boost::regex e; e.imbue(std::locale("en_US")); e.assign(my_regular_expression); // now uses en_US as it's locale HTH, John.
