Unicode in strings

[Cecil Ward]

How do I get a wstring or dstring with a code point of 0xA0 in it 
? That’s a type of space, is it? I keep getting a message from 
the LDC compiler something like "Outside Unicode code space" in 
my unittests when this is the first character in a wstring. I’ve 
tried all sorts of escape sequences but I must simply be 
misunderstanding the docs. I could always copy-paste a real live 
one into a double quoted string and be done with it, I suppose.
