String Encoding Error in Notebook output

[4Urban]

System details

RStudio Edition : Desktop
RStudio Version : RStudio 1.4.1066
OS Version      : Windows 10/8/7 (64-bit)
R Version       : R x64 4.0.3

Steps to reproduce the problem

To reproduce the problem, no need to get any data.
It occurs at any time when logging any character that is not the English alphabet.

For example, when running the below code for the first time, the result is as follows.

library(dplyr)

It's same in the console.

Describe the problem in detail

However, if I run the same code in the console for the first time(not again, after restarting the R), it prints without any error.

That is, I get an error ONLY when I interact in the Notebook console.

Below is my basic settings in the Notebook.

Describe the behavior you expected

I want to get correctly encoded messages in the Notebook console as same as in the console.

• I have read the guide for submitting good bug reports.
• I have installed the latest version of RStudio, and confirmed that the issue still persists.
• If I am reporting a RStudio crash, I have included a diagnostics report.
• I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.

Note for testing: to get Korean output on an English copy of Windows, you'll need to activate a Korean locale and also request Korean message translations. This can be done with:

Sys.setlocale(locale = "Korean")
Sys.setenv(LANGUAGE = "ko")

[kevinushey]

Interestingly, errors are properly translated -- it appears just package startup messages (and perhaps other conditions) are the problem?

[4Urban]

You're right. I can reproduce that problem only when starting packages too. In my memory, all the error messages in Korean also showed the same problem before, but it doesn't not now except startup.

I'll comment later when I get the same problem in other conditions.

But can you inspect what causes that problem?

Thank you!

[kevinushey]

This is indeed an RStudio issue: we're not properly handling the encoding of R conditions. Will keep taking a look!

[4Urban]

Ok! Thank you!

Fixed in Juliet Rose via #8565.

@kevinushey Thank you for the fast fixing!

Verified Fixed

RStudio Edition : Desktop
RStudio Version : 1.4.1545
OS Version      : Windows 10
R Version       : 4.0.3

Verified that package startup messages in Notebook and Console are now properly UTF-8 encoded. Tested with the Korean language.
