Assignment of `std::vector<std::string>` gives unexpected results

[maarten-ic]

Assigning a vector of strings to an HDC node compiles successfully (unless -DDEBUG is defined), but the result is unexpected:

#include <hdc.hpp>

int main() {
    HDC test;
    test["vector_of_strings"] = std::vector<std::string>({"string 1", "string 2"});
    test.dump();
    return 0;
}

Results in output

{
        "vector_of_strings" : "\u043d\u022cgU"
}

Expected behaviour:

• If this is supported, I would expect to either see an array of strings (or potentially a 2D character array) in vector_of_strings
• If this is an unsupported use-case, a compile-time error should prevent assignment of a std::vector<std::string>
