    “Unicode string” really isn’t specific enough to know what your source data is, but you probably mean ‘UTF-16 string stored as wchar_t array’ since that’s what most people who don’t know the correct terminology use.

    “char*” also isn’t enough to know what you want to target, although maybe “embarcadero” has some convention. I’ll just assume you want UTF-8 data unless you mention otherwise.

    Also I’ll limit my example to what works in VS2010

    // your "Unicode" string
wchar_t const * utf16_string = L"Hello, World!";

// #include <codecvt>
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>,wchar_t> convert;

std::string utf8_string = convert.to_bytes(utf16_string);

    This assumes that wchar_t strings are UTF-16, as is the case on Windows, but otherwise is portable code.
