Cc'ing Kurt since the version control history shows he brought it in a
few years ago: https://github.com/wch/r-source/commit/53d4b432f7
The fix can be fairly simple if someone has one minute:
lc_ctype <- Sys.getlocale("LC_CTYPE")
on.exit(Sys.setlocale("LC_CTYPE", lc_ctype), add = TRUE)
Sys.setlocale("LC_CTYPE", "C")
although I do not really understand why LC_CTYPE has to be changed to "C".
