I'd forgotten about it until reading this, but I think you can get
into trouble with Unicode normalisation as well - so, I think we can
safely dismiss this as an irrelevant tangent and just stick with
Antoine's basic Windows vs Posix distinction. If need be, the
strategies can be exposed at a later date (via keyword-only arguments)
if we come up with a more convincing use case.

Cheers,
Nick.
