garbled R code received from others

Select File>Reopen with Encoding... from the RStudio menu to change the encoding and reopen the file.
In Japanese,

• CP932
• SHIFT-JIS
• UTF-8
• ISO 2022-JP

I think it's one of the .

If you edit and save garbled characters, re-opening with the correct encoding may not fix garbled characters.
If so, try downloading the script again.

The garbled files from the Windows environment are a problem.

The reason for garbled characters is that the character code is not UTF8.
In my case, I always use utf8 first for files that come from outside, and
I try to share it.

Below is a sample code for Mac/Linux

for fin`ls*.csv`
do
    iconv-fcp932-tutf-8<$f>utf8-$f
done

Here's an additional note on October 2019.The behavior of the above changes depending on the shell, so
I think it's better to use nkf, a great command that correctly translates any character code into Japanese UTF-8.

 sudo apt install nkf
find./-name '*.tsv'-print 0 | xargs-0nkf-Lu-w --overwrite
