问题
I am working with some special characters in Rstudio. It coverts them into plain letters.
print("Safarzyńska2013")
[1] "Safarzynska2013"
x <- "Māori"
x
[1] "Maori"
Is there any way to read in the exact original characters. Following info might be helpful: Rstudio default encoding is UTF-8
sessionInfo()
R version 3.1.1 (2014-07-10)

This not an exclusively RStudio problem.
Typing print("Safarzyńska2013") on the console of RGui also converts them to plain letters. Running this code from an UTF-8 encoded Script in RGui returns [1] "Safarzy?ska2013".
I don't think that it is a good idea to type such special chars on the console. x <- "SomeString"; Encoding(x) returns "unknown" and that is probably the problem: R has no idea what encoding you are using on the console and probably has no chance to get your original encoding.
I put "Safarzyńska2013\nMāori\n" in a text file encoded with UTF-8. Then the following works fine:
tbl <- read.table('c:/test1.txt', encoding = 'UTF-8', stringsAsFactors = FALSE)
tbl[1,1]
tbl[2,1]
Encoding(tbl[1,1]) # returns "UTF-8"
If you really want to use the console, you probably will have to mask the special chars. In ?Encoding we find the following example to create a word with special chars:
x <- "fa\xE7ile"
Encoding(x)
Actually I don't know at the moment how to get these codes for your special chars and ?Encoding has also no hints...

Go to the label File of RStudio, them click on Save with encoding... , Choose Encoding UTF-8 , Set as default encoding for source file and save.
Hope this helps
