--- Comment #1 from Dennis <dkorpel at live.nl> ---
This is relevant when e.g. converting a `ubyte[]` to a `wchar[]` or `dchar[]`,
but I don't think the language ever does that itself. A `wchar` and `dchar` are
defined as "unsigned 16/32 bit" basic types, just like `ushort` or `uint`, and
endianness in general is already specified to be target defined here:

https://dlang.org/spec/abi.html#endianness

Would it suffice to add char types to the table below it?
