Duncun, thank you for your reply. My encoding is: > Sys.getlocale('LC_CTYPE') [1] "Czech_Czech Republic.1250"
In RStudio I use UTF-8. I tried also other recommended encodings but some characters are still misrepresented. I've found solution to this. To correctly display strings in RStudio I have to convert strings: iconv(x,"CP1250","UTF-8") If I want to write string into file: zz=file("myfile.txt", "w", encoding="UTF-8") cat(x,file = zz, sep = "\n") It seems there is no need using icon() if I just need to write string to a file. I hope there is no problem processing strings with other functions like paste, strsplit, grep though.
