Hex code '\a0' crashes language server

[ManuelHentschel]

Setup:

• windows 10
• vscode v1.87.2
• R v4.3.3
• languageserver v0.3.16 (installed from GitHub)

Workspace containing a single file named "test.R" with content:

'\xa0'

Error:
Having this file open and reloading the vscode windows produces the following Error messages:
"Connection to server got closed. Server will not be restarted." (Source: R)
"Client R Language Server: connection to server is erroring. read ECONNRESET" (Source: R)

R Language Server output channel contains:

Notes:
I could not reproduce using wsl.
The file name does not seem to be the issue, the error does not occur with different file contents.
If I start with an empty file and add the text '\xa0', the languageserver usually does not crash and features like Go to Definition work on the following:

s <- '\xa0'

s

I'm getting the same (or only similar error, but with a different cause:

From the second step of the stack trace onwards, it's almost identical.

Just having "T\x81rkiye" uncommented in my script crashes R language server which is used for linting (VS code + R extension)

Client R Language Server: connection to server is erroring. read ECONNRESET

The exact line is:
mutate(ISO3 = recode(ISO3, "T\x81rkiye" = "Türkiye"))

I think that's basically #640 . I get the same message. Would be great to find a solution for this!
