Boost Regex and Unicode in C++ Builder

Boost - Bast C++ Library

Because "String" default is unicode in C++ Builer 2009 later.

And same std::wstring.

so, We should to use prefix "w" class, like:
wregex, wsmatch etc.

The Sample code below:

1 2 3 4 5 6 7 8 9 10 11 12

//#include <boost/regex.hpp> std::wstring line; //line = Edit1->Text.c_str(); line = String(u"ようこそ456").c_str(); std::wstring text; //boost::wregex regExp(Edit2->Text.c_str()); boost::wregex regExp(String(u"56").c_str()); boost::wsmatch what; if (boost::regex_search(line, what, regExp)) { text = std::wstring(what[0].first, what[0].second); ShowMessage(text.c_str()); }
