The first print statement below works fine but not the second.  The second one generates the error "Expected '}" in \u{...} escape sequence".  (They should (in theory) be the same,)
print("\u{F0A5}")
let generatedValue = "F0A5"
print("\u{\(generatedValue)}")
I've tried various formatting tricks without success. How do I overcome this error to produce an escaped special character string on the fly?
