I've got a function which takes two strings and should return
them as a ubyte[] with additional zero bytes in between and
around. This works:
ubyte[] convert_string_pair(string first, string second)
{
auto b = new ubyte[](0);
b ~= 0x00 ~ first ~ 0x00 ~ second ~ 0x00;

The reason is, that this expression creates a string and not a
ubyte[]...
it should be ok to just cast it in this case.

Thank you for the replay.
Now I know.

I don't know about the error you're seeing, but the generic way
to get an array of the underlying data type of a string is via
std.string.representation.

Of course, if you need a mutable array you should dup:
auto bytes = cast(ubyte[])s.dup;
Not only "should" but he "must" otherwise
