Putting \usepackage[cp1252]{inputenc} into my preamble is not an option,
because XeTeX unlike LaTeX needs UTF-8 has input encoding. My goal is also
to have a LyX document that can be compiled both on Mac and Windows.I usually compile my Lyx-Sweave documents by one click of a button from within Lyx. R code chunks are therefore executed by calling R from the command line. If anybody knows how to run R with options(encoding="UTF-8") from the command line under windows, that would be helpful. The command that calls R during compilation is contained in this file: http://cran.r-project.org/contrib/extra/lyx/preferences Regards, Erich -----Ursprüngliche Nachricht----- Von: Duncan Murdoch [mailto:murdoch.dun...@gmail.com] Gesendet: Mittwoch, 12.

The line above will convert the native encoding to UTF-8. That's probably fine, but it's not actually helpful. The problem is that when R outputs a vector, it will convert it back to the native encoding, unless you take action to stop that. If you don't mind changing your document for Windows, you can put \usepackage[cp1252]{inputenc} into the preamble, and use the Windows native CP1252 encoding throughout. If you want something that will work in UTF-8 on Windows, you need to say options(encoding="UTF-8") *before* running Sweave. (If you're running Sweave from the command line using "R CMD Sweave" then I don't know if you can specify the output encoding; it won't help to do it in the document code chunks). You also need to put the line \usepackage[utf8]{inputenc} into the document preamble, but it sounds as though Lyx has already done that for you.
