Like the c'tor call, but using assign instead ;-):

void from_vector(std::wstring& dst, const std::vector<wchar_t>& src) {
    dst.assign(src.begin(), src.end());
}

This call is semantically equivalent to:

dst.assign(wstring(src.begin(), src.end()));

The c'tor template accepts any InputIterator with value type convertible
to the value_type of the corresponding basic_string.

[N.B.: If InputIterator is actually an integral type the standard 
requires that instead of a sequence constructor the constructor is
invoked which creates astring of given size with given character value]
