R help - Oct 2014 - [Sweave] doesn't accept unicode?

Of course I manage and write my tex-files in unicode (utf-8) (running 
XeTeX). That is why my R-output need to be in unicode, too.

But Sweave doesn't accept unicode files.

[R]
> Sweave("analy.Snw")
Fehler: ?analy.Snw? is not ASCII and does not declare an encoding
[/R]

[analy.Snw]
<<>>x <- ?

table(x)
@
[/analy.Snw]

How should I "declare an encoding". I can not find an option for the 
<<>>.

I don't have to declare any of my tex-files explicite because XeTeX use 
the files like they come. It knows for itself the encoding.

Look at here for an example using an encoding in knitr:
