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.
