How to convert wstring into byte vector

byte, c++, type-conversion, wstring

Solution

Byte const* p = reinterpret_cast<Byte const*>(&str[0]);
std::size_t size = str.size() * sizeof(str.front());
ByteVector vect(p, p+size);

Problem

Hi I have a few typedefs: ``` typedef unsigned char Byte; typedef std::vector<Byte> ByteVector; typedef std::wstring String; ``` I need to convert `String` into `ByteVector`, I have tried this: ``` String str = L"123"; ByteVector vect(str.begin(), str.end()); ``` As a result `vectror` contains 3 elements: 1, 2, 3. However it is `wstring` so every charcter in this string is wide so my expected result would be: 0, 1, 0, 2, 0, 3. Is there any standart way to do that or I need to write some custom function.
