It is probably not very well documented, but you want to use setlocale in order to use Chinese. And the method applies to many other languages as well. The solution is not obvious as the official document of setlocale didn't specifically mentioned it as a method to solve the display issues.

> print('ÊÔÊÔ') #试试, meaning let's give it a shot in Chinese
[1] "ÊÔÊÔ" #won't show up correctly
> Sys.getlocale()
[1] "LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252"
> Sys.setlocale(category = "LC_ALL", locale = "chs") #cht for traditional Chinese, etc.
[1] "LC_COLLATE=Chinese_People's Republic of China.936;LC_CTYPE=Chinese_People's Republic of China.936;LC_MONETARY=Chinese_People's Republic of China.936;LC_NUMERIC=C;LC_TIME=Chinese_People's Republic of China.936"
> print('试试')
[1] "试试"
> read.table("c:/CHS.txt",sep=" ") #Chinese: the 1st record/observation
  V1   V2  V3 V4  V5   V6

If you just want to change the display encoding, without changing other aspects of locales, use LC_CTYPE instead of LC_ALL:

> Sys.setlocale(category = "LC_CTYPE", locale = "chs")
[1] "Chinese_People's Republic of China.936"
> print('试试')
[1] "试试"

Now, of course this only applies to the official R console. If you use other IDE's, such as the very popular RStudio, you don't need to do this at all to be able to type and display Chinese, even if you didn't have the Chinese locale loaded.

Migrate some useful stuff from the following comments:

If the data still fails to show up correctly, the we should also look into the issue of the file encoding. If the file is UTF-8 encoded, tither data <- read.table("you_file", sep=',', fileEncoding="UTF-8-BOM", header=TRUE) or fileEncoding="UTF-8" will do, depends on which encoding it really has.

But you may want to stay away from UTF-BOM as it is not recommended: What's different between UTF-8 and UTF-8 without BOM?

  • can i wirte it into a configuration file? – showkey Jul 02 '14 at 05:13
  • Yep, it is called **startup file**, see this: http://www.statmethods.net/interface/customizing.html – CT Zhu Jul 02 '14 at 06:24
  • With your permission. May I suggest change the title to `...chinese (and other non-ASCII) character in r console?`, the issue is not really Chinese specific and others may benefit from it as well. – CT Zhu Jul 02 '14 at 06:31
  • a last problem about the post : if the data file (http://pan.baidu.com/s/1hqklUfU) is in the form of ansi,chinese character can be displayed properly,if data file is saved as the form of utf, same read.table command can not display the chinese character ,it is a garbled character. please resave the data file in the form of utf-8 with notepad,and try `read.table("r1.csv",sep=",")`.how can i do then if the data file is utf8 form? – showkey Jul 02 '14 at 07:16
  • You can change all the data files with notepad in the form of ansi,and open it in r with read.table, is there a another way to do ? – showkey Jul 02 '14 at 07:19
  • No, you don't have to. Try either `data – CT Zhu Jul 02 '14 at 16:17
  • I tried set locale but it does not work. I have a chinese win 10 and chinese r.base. still, not print chinese when it is in R studio – News_is_Selection_Bias Jul 26 '16 at 03:48
