This looks like an encoding problem: there are several different standards for encoding non-ASCII characters. All of your tools have to agree on the encoding. To my eye it looks as though in the first case R is writing out UTF-8, and whatever you are using to look at your .tex file is assuming latin1 (some Windows programs say "ANSI", but I think that doesn't fully specify the encoding: you also need a code page, which is set somewhere in Windows control panel.) The functions related to encodings in R are: options(encoding="latin1") - set the default encoding iconv(x, from="latin1", to="UTF-8") - re-encode entries, mapping each character from one encoding to the other Encoding(x) - display the encoding of each entry (unknown means ascii or the native encoding for your platform) Encoding(x) <- "latin1" - change the declared encoding, without changing the bytes.
