How do I convert wchar_t* to string?

I am new to C++.

And I am trying to convert wchar_t* to string.

I cannot use wstring in condition.

I have code below:

wchar_t *wide   = L"中文";
wstring ret     = wstring( wide );
string str2( ret.begin(), ret.end() );

But str2 returns some strange characters.

Where do I have to fix it?

I'm not sure what platform you're targeting. If you're on Windows platform you can call WideCharToMultiByte API function. Refer to MSDN for documentation.

If you're on Linux, I think you can use libiconv functions, try google.

Of course there is a port of libiconv for Windows.

In general this is a quite complex topic for a new beginners if you know nothing about character encodings - there are a lot of background knowledge to have to learn.

You're trying to do it backwards. Instead of truncating wide characters to chars (which is very lossy), expand your chars to wide characters.

That is, transform your std::string into an std::wstring and concatenate the two std::wstrings.
