Dear all, One of the unit tests for my package breaks only on r-devel under Windows ( https://cran.r-project.org/web/checks/check_results_git2rdata.html). The unit test sorts a set of UTF-8 characters and writes them to disk. I've noticed that the Euro symbol (?) gets a different place in r-devel under Windows 10 compared to over combinations of R version and OS. I know that sorting depends on the locale. Therefore I set the locale to "C" prior to sorting. See the function below. After sorting, I reset the locale to the existing one. Is there something that I'm missing? Best regards, Thierry set_c_locale <- function() { old_ctype <- Sys.getlocale(category = "LC_CTYPE") old_collate <- Sys.getlocale(category = "LC_COLLATE") old_time <- Sys.getlocale(category = "LC_TIME") old_monetary <- Sys.getlocale(category = "LC_MONETARY") Sys.setlocale(category = "LC_CTYPE", locale = "C") Sys.setlocale(category = "LC_COLLATE", locale = "C") Sys.setlocale(category = "LC_TIME", locale = "C") Sys.setlocale(category = "LC_MONETARY", locale = "C") return( c( ctype = old_ctype, collate = old_collate, time = old_time, monetary = old_monetary ) ) } ir.
