I don't think that Windows-1250 a.k.a cp1250 encoding is unusual usage case
as it is default native encoding for Rgui on Windows XP in Slovenia,
Slovakia, Hungary, Czech Republic, Romania, Albania, Croatia, Bosnia and

I'm providing minimal example, it's a modified example from Sweave

%%%%%%%%%%% file: example-1.Rnw

\documentclass[a4paper]{article} \usepackage[slovene]{babel}
\usepackage[cp1250]{inputenc} \usepackage[T1]{fontenc}  

\title{Sweave Example 1} \author{Friedrich Leisch}



In this example we embed parts of the examples from the \texttt{kruskal.test}
help page into a \LaTeX{} document:

<<>>= data(airquality, package="datasets") library("stats")
kruskal.test(Ozone ~ Month, data = airquality) @ which shows that the
location parameter of the Ozone distribution varies significantly from month
to month. Finally we include a boxplot of the data:

\begin{center} <<fig=TRUE,echo=FALSE>>= library("graphics") boxplot(Ozone ~
Month, data = airquality) @ \end{center}
