citep error for dplyr package citation - Windows

[melindahiggins2000]

Here is my reproducible example. When I use citep() with the citation() function, I get an error. I'm running Windows 10, R 3.4.3; RStudio 1.1.383. My sessionInfo() is listed below, along with the code that produces the error Error in nchar(aut) : invalid multibyte string, element 1.

Note: citep() works fine for most of the other packages I'm currently citing in my project. I would appreciate any suggestions on how to fix this citation for the dplyr package.

To cite package ‘dplyr’ in publications use:

  Hadley Wickham, Romain Francois, Lionel Henry and
  Kirill Müller (2017). dplyr: A Grammar of Data
  Manipulation. R package version 0.7.4.
  https://CRAN.R-project.org/package=dplyr

A BibTeX entry for LaTeX users is

  @Manual{,
    title = {dplyr: A Grammar of Data Manipulation},
    author = {Hadley Wickham and Romain Francois and Lionel Henry and Kirill Müller},
    year = {2017},
    note = {R package version 0.7.4},
    url = {https://CRAN.R-project.org/package=dplyr},
  }

Seems to be related to how Windows is handling the UTF-8 characters (controlled by your locale settings), but not sure quite where it goes wrong (don't have a Windows box handy to debug, can't reproduce the error on Linux + Mac).

Can you try:

citep( RefManageR::as.BibEntry(citation("dplyr") ) )

[melindahiggins2000]

I still get the same error - here are my code results:

> RefManageR::as.BibEntry(citation("dplyr"))
[1] H. Wickham, R. Francois, L. Henry, et al. _dplyr: A
Grammar of Data Manipulation_. R package version 0.7.4.
2017. <URL: https://CRAN.R-project.org/package=dplyr>.

> citep(RefManageR::as.BibEntry(citation("dplyr")))
Error in nchar(aut) : invalid multibyte string, element 1

By the way, this is not a show stopper when I'm running it inside of my Rmarkdown document. The document does compile, but this is what I get for the dplyr reference in my document - basically the authors are stripped off. Something in the dplyr author list is causing the issue, I think...
