OK, so I'm told that Windows uses UTF-16.

Looks like Mono uses UTF-8, which we've been transparently relying on.

So the fix here in the C# binding is to for us convert the string to
UTF-8 before giving it to the Redland method.

Dave might want to speculate on whether Unicode-aware parameter
processing might be something useful to add to Redland as well, but we
can get round the immediate problem in the C# bindings.

I'll try to get some time to work on this, unless you'd like to take a
crack.
