There's a trick though:
Handle<String> BinaryString(const uint8_t* data, size_t size) {
uint16_t* out = new uint16_t[size];
for (size_t n = 0; n < size; ++n) out[n] = data[n];
Local<String> s = String::NewFromTwoByte(Isolate::GetCurrent(), out);
delete[] out;
return s;
}
There's room for optimization of course, but the basic concept is the
same: convert the input to 16 bits and create a two-byte string from
that.
