Description

The character u+100 is not found using the regex pattern[[:unicode:]].

Here sample :
#include <boost/regex.hpp>
#include <iostream>
using namespace std;
using namespace boost;

int main()
{
	wregex re(L"[[:unicode:]]");
	wstring wstr=L"\u0100";

	if(regex_match(wstr,re))
		cout<<"Match "<<endl;
	else
	{
		cout<<"Not match"<<endl;
	}
	return 0;
}


'Not match' is displayed.
