I don't think this is correct. Cross platform restores are allowed,  
and should work. There might be issues with character set encodings,  
but apart from that, it's portable. Even endian issues are carefully  
taken into account.

We should keep on supporting cross-platform restores.

These platforms issues should be isolated in the client -- as I note  
Chris is doing.

Internally, I think standardising on UTF-8 is the way to go. It seems  
to be the approach taken by the major OS vendors for POSIX access to  
filing systems, and is sensible.
