Cannot type the "±" symbol in Radian on Windows platforms.

[yanpd01]

operating environment

radian version: 0.6.2
r executable: C:\R\R-4.2.0\bin\R
r version: 4.2.0
python executable: C:\Users\cuilab\AppData\Local\Programs\Python\Python310\python.exe
python version: 3.10.4
windows 10 21H2: 19044.1645
system language: Chinese (People's Republic of China)

problem description

Whether running radian in CMD or Powershell, or directly opening radian.exe, I cannot type "±". Even the URLdecode("%C2%B1") function doesn't print "±" correctly, but everything looks fine in Linux.

what does Sys.getenv("LANG") return?

what does Sys.getenv("LANG") return?

Enter Sys.getenv("LANG"), it will be displayed as "en_US.UTF-8" in radian and "" in the R console. When I set Sys.setenv(LANG="") in radian, I still can't type and print ±. But everything works fine in the R console.

The workaround of setting LANG was inspired by #269 (comment)

@SpecterShell
Could you reproduce the same bug here?

[SpecterShell]

The same here, but may not relate to that change. 🧐

While %C2%B1 maps to ± in UTF-8, it maps to 卤 in GB2312.

Default GB2312 (936) in console, GB2312 (936) in radian

Set UTF8 (65001) in console, GB2312 (936) in radian

Default GB2312 encoding (936) in console, UTF-8 (65001) in R

When I run Sys.setlocale(locale ="Chinese (Simplified)_China.UTF-8"), I can type and print "±" normally. But running this code throws a warning, will this affect other operations?

[randy3k]

Indeed, it is a locale related stuff. Python on Windows doesn't support UTF-8 as default codepage, so it inherits the system locale, which is simplified chinese in your case.

I think it should be safe to ignore the warning in this case as R 4.2 indeed does support UTF-8 codepage.

[yanpd01]

I am going to write Sys.setlocale(locale ="Chinese (Simplified)_China.UTF-8") into the .Rprofile file, in order to use the radian better.
Thanks for your answer.
