This is about the only valid use case I can think of. And it's really
only useful in druntime/Phobos test cases. I can't imagine users would
go out of their way to use generate binary test data where string input
is desired.

Uhm... strings that aren't in UTF format really ought to be ubyte[]
(resp. ushort[], uint[]), not string, because pretty much everything in
D that takes a (|w|d)string argument expects UTF encoding.

(Or, in an ideal world where std.encoding is actually sane, we'd use
suitable wrapper types for ubyte[] that represent their respective

Again, shouldn't these be ubyte[]? Calling them string (i.e.
immutable(char)[]) is a wrong conflation of ubyte with char, that has
led to so much headache in C/C++. D should not repeat this mistake.
