How to source() .R file saved using UTF-8 encoding?

encoding, file-io, internationalization, r, utf-8

Solution

We talked about this a lot in the comments to my previous post but I don't want this to get lost on page 3 of comments: You have to set the locale, it works with both input from the R-console (see screenshot in comments) as well as with input from file see this screenshot:

The file "myfile.r" contains:

russian <- function() print ("Американские с...");

The console contains:

source("myfile.r", encoding="utf-8")
> Error in source(".....
Sys.setlocale("LC_CTYPE","ru")
> [1] "Russian_Russia.1251"
russian()
[1] "Американские с..."

Note that the file-in fails and it points to the same character as the original poster's error (the one after "R). I can not do this with Chinese because i would have to install "Microsoft Pinyin IME 3.0", but the process is the same, you just replace the locale with "chinese" (the naming is a bit inconsistent, consult the documentation).

Problem

The following, when copied and pasted directly into R works fine: ``` > character_test <- function() print("R同时也被称为GNU S是一个强烈的功能性语言和环境,探索统计数据集,使许多从自定义数据图形显示...") > character_test() [1] "R同时也被称为GNU S是一个强烈的功能性语言和环境,探索统计数据集,使许多从自定义数据图形显示..." ``` However, if I make a file called character_test.R containing the EXACT SAME code, save it in UTF-8 encoding (so as to retain the special Chinese characters), then when I source() it in R, I get the following error: ``` > source(file="C:\\Users\\Tony\\Desktop\\character_test.R", encoding = "UTF-8") Error in source(file = "C:\\Users\\Tony\\Desktop\\character_test.R", encoding = "utf-8") : C:\Users\Tony\Desktop\character_test.R:3:0: unexpected end of input 1: character.test <- function() print("R 2: ^ In addition: Warning message: In source(file = "C:\\Users\\Tony\\Desktop\\character_test.R", encoding = "UTF-8") : invalid input found on input connection 'C:\Users\Tony\Desktop\character_test.R' ``` Any help you can offer in solving and helping me to understand what is going on here would be much appreciated. ``` > sessionInfo() # Windows 7 Pro x64 R version 2.12.1 (2010-12-16) Platform: x86_64-pc-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=English_United Kingdom.1252 [2] LC_CTYPE=English_United Kingdom.1252 [3] LC_MONETARY=English_United Kingdom.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United Kingdom.1252 attached base packages: [1] stats graphics grDevices utils datasets methods [7] base loaded via a namespace (and not attached): [1] tools_2.12.1 ``` and ``` > l10n_info() $MBCS [1] FALSE $`UTF-8` [1] FALSE $`Latin-1` [1] TRUE $codepage [1] 1252 ```
