That blog post is not entirely correct about UTF-8: if you use pdflatex, you have to declare the font encoding \usepackage[T1]{fontenc} when you save the document with UTF-8, e.g. the following minimal example should work with pdflatex + knitr in RStudio with UTF-8:
\documentclass{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \begin{document} <<>>= degree <- "°" print(degree) @ \end{document} For XeTeX, you will have to use different packages, fontspec and xunicode. Here is a minimal example for XeTeX: \documentclass{article} \usepackage{fontspec} \usepackage{xunicode} \begin{document} <<>>= degree <- "°" print(degree) @ \end{document} Similar things apply to ü. You need to specify the argument `encoding = 'UTF-8'` when calling Sweave() or knitr::knit().

It knows for itself the encoding. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
