Recently I was trying to cite a package where the authors have ä
and ø in their names. I found that on Windows the citation() function
did not return the authors' names at all, but on Linux there was no
problem (sessionInfos at the bottom):
On Windows, no author names are returned:
#---------------
> citation("readr")
To cite package ‘readr’ in publications use:
(2017). readr: Read Rectangular Text Data. R package version 1.1.1.
https://CRAN.R-project.org/package=readr
A BibTeX entry for LaTeX users is
@Manual{,
title = {readr: Read Rectangular Text Data},
year = {2017},
note = {R package version 1.1.1},
url = {https://CRAN.R-project.org/package=readr},
}
ATTENTION: This citation information has been auto-generated from the
package DESCRIPTION file and may need manual editing, see
‘help("citation")’.
#---------------
On Linux we do see the author names:
#---------------
> citation("readr")
To cite package ‘readr’ in publications use:
Hadley Wickham, Jim Hester and Romain Francois (2017). readr:
Read Rectangular Text Data. R package version 1.1.1.
https://CRAN.R-project.org/package=readr
A BibTeX entry for LaTeX users is
@Manual{,
title = {readr: Read Rectangular Text Data},
author = {Hadley Wickham and Jim Hester and Romain Francois},
year = {2017},
note = {R package version 1.1.1},
url = {https://CRAN.R-project.org/package=readr},
}

This appears to be an OS-dependent encoding issue. The citation function
does not take an encoding argument, so it's not possible to set the
encoding at the point where that function is used. The citation function
working with the packageDescription function, which does have an
encoding argument, but the default is not useful for Windows when there
is an encoding set in the DESCRIPTION of the package (in this case UTF-8).
We can set the encoding argument in packageDescription so it works in
Windows to give the authors as expected, but it is very inconvenient to
generate citations directly from the output of this function. So I'd
like to propose a solution this problem by changing one line in the
packageDescription function, like so, from:
#---------------
if (missing(encoding) && Sys.getlocale("LC_CTYPE") == "C")
#---------------
to:
#---------------
if ((missing(encoding) && Sys.getlocale("LC_CTYPE") == "C") |
unname(Sys.info()['sysname']) == "Windows")
#---------------
If I understand correctly, that will force ASCII//TRANSLIT encoding when
DESCRIPTION files are read by packageDescription() on Windows machines.
The upside is that Windows users will get the authors in the package
citation, unlike the current situation. The downside is that the exotic
symbols in the authors' names are replaced with common ones that are
similar.
I think getting the citations to easily include the authors' names is
pretty important, even if their names have exotic characters, so this is
worth fixing. Is this edit to packageDescription the best way to solve
this problem of exotic characters preventing the authors' names from
showing on Windows?
thanks,
Ben
