本文介绍了两种字符编码转换的方法：从char类型转换到wchar类型以及从wchar类型转换回char类型。这两种方法使用了C++标准库中的MultiByteToWideChar和WideCharToMultiByte函数来实现不同字符集间的转换。

std::wstring CharToWchar(const char* c, size_t m_encode = CP_ACP)
{
	std::wstring str;
	int len = MultiByteToWideChar(m_encode, 0, c, strlen(c), NULL, 0);
	wchar_t*	m_wchar = new wchar_t[len + 1];
	MultiByteToWideChar(m_encode, 0, c, strlen(c), m_wchar, len);
	m_wchar[len] = '\0';
	str = m_wchar;
	delete m_wchar;
	return str;
}



 
std::string WcharToChar(const wchar_t* wp, size_t m_encode = CP_ACP)
{
	std::string str;
	int len = WideCharToMultiByte(m_encode, 0, wp, wcslen(wp), NULL, 0, NULL, NULL);
	char	*m_char = new char[len + 1];
	WideCharToMultiByte(m_encode, 0, wp, wcslen(wp), m_char, len, NULL, NULL);
	m_char[len] = '\0';
	str = m_char;
	delete m_char;
	return str;
}
