Hello,
I'm encountering what seems to be a bug when using the `writeClipboard()`
function in the R {utils} package.
When I try to copy text to the clipboard, I notice that I get extra characters
when I try to paste it (by hand with CTRL+V or with the `readClipboard()`
function from R packages {utils}).
Here's my example:
``` r
utils::writeClipboard("plot(AirPassengers)")
for (k in 1:10) {
print(utils::readClipboard())
}
#> [1] "plot(AirPassengers)" "⤀攀"
#> [1] "plot(AirPassengers)" "\u0a00"
#> [1] "plot(AirPassengers)" "\xed\xb0\x80ư"
#> [1] "plot(AirPassengers)"
#> [1] "plot(AirPassengers)"
#> [1] "plot(AirPassengers)"
#> [1] "plot(AirPassengers)"
#> [1] "plot(AirPassengers)"
#> [1] "plot(AirPassengers)" "⤀"
#> [1] "plot(AirPassengers)"
Message d'avis :
Dans utils::readClipboard() : unpaired surrogate Unicode point dc00
```
So I don't always get the same result.
I opened a problem in the {clipr} GitHub repository before realizing it's a
{tools} problem: https://github.com/mdlincoln/clipr/issues/68
Is this a bug or something I haven't configured properly?
Thank you very much

Hello,
I have reproduced part of the behavior in the OP but it will depend on
the GUI or command line used.
With Rscript or with R I haven't found any errors.
With Rgui or with RStudio, yes, the output was not the expected output.
All code run in R 4.4.0 on Windows 11.
The script rscript.R is
utils::capture.output({
utils::writeClipboard("plot(AirPassengers)")
for (k in 1:10) {
print(utils::readClipboard())
}
sessionInfo()
}, file = "rhelp.txt")
