Unicode version of base64 encoding/ decoding
- by Yan Cheng CHEOK
I am using base64 encoding/decoding from http://www.adp-gmbh.ch/cpp/common/base64.html
It works pretty well with the following code.
const std::string s = "I Am A Big Fat Cat" ;
std::string encoded = base64_encode(reinterpret_cast<const unsigned char*>(s.c_str()), s.length());
std::string decoded = base64_decode(encoded);
std::cout << _T("encoded: ") << encoded << std::endl;
std::cout << _T("decoded: ") << decoded << std::endl;
However, when comes to unicode
namespace std
{
#ifdef _UNICODE
typedef wstring tstring;
#else
typedef string tstring;
#endif
}
const std::tstring s = _T("I Am A Big Fat Cat");
How can I still make use of the above function?
Merely changing
std::string base64_encode(unsigned TCHAR const* , unsigned int len);
std::tstring base64_decode(std::string const& s);
will not work correctly.
(I expect base64_encode to return ASCII. Hence, std::string should be used instead of std::tstring)
