在unicode模式下，如何同時接受寬字符和窄字符，並且接受不同變量的debug輸出：

#include<windows.h>
#include<iostream>
#include<string>
#include<cassert>

//first;
template<typename T>
class IsWchar;

template<>
class IsWchar<char>
{
public:
    static const int theType = 0;
};

template<>
class IsWchar<char*>
{
public:
    static const int theType = 0;
};
template<>
class IsWchar<const char*>
{
public:
    static const int theType = 0;
};

template<>
class IsWchar<wchar_t>
{
public:
    static const int theType = 1;

};
template<>
class IsWchar<const wchar_t>
{
public:
    static const int theType = 1;

};
template<>
class IsWchar<wchar_t*>
{
public:
    static const int theType = 1;

};

template<>
class IsWchar<const wchar_t*>
{
public:
    static const int theType = 1;

};

//second;
template<int num,typename vT>
class Decision;

template<typename vT>
class Decision<0, vT>
{
public:
    static void PTSTR(vT var)
    {
        int length=strlen(var);
        assert(length != 0);
        wchar_t* pWchar = new wchar_t[(length + 1)*2];
        for (int i = 0; i < length;++i)
        {
            pWchar[i] = var[i];
        }
        pWchar[length] = L'\0';
        OutputDebugString(pWchar);
        delete[] pWchar;
    }

};

template<typename vT>
class Decision<1, vT>
{
public:
    static void PTSTR(vT var)
    {
        OutputDebugString(var);
    }

};

//3
template<typename vT>
void debugPrint(vT string_)
{
    Decision<IsWchar<vT>::theType, vT>::PTSTR(string_);
    OutputDebugString(L"\n");
}

template<typename vT,typename T2>
void debugPrint(vT string_,T2 var)
{
    Decision<IsWchar<vT>::theType, vT>::PTSTR(string_);
    OutputDebugString(std::to_wstring(var).c_str());
    OutputDebugString(L"\n");
}

int main()
{
    debugPrint("aaa");
    debugPrint(L"bbb");
    debugPrint("something ", 15);
    debugPrint(L"something ", 16.2);

    getchar();
    return 0;
}
