Hi, before I start: this is a cross posting of a related SO issue by someone else that also bugs me:
Of course I will update both issues in case of a solution.
So, whenever I launch R or RStudio (R 3.5.2 with latest RTools) on Windows 10, I am getting the warning:
During Startup - Warning message: Setting LC_CTYPE = failed
There seem to be several solutions for Mac OS and also some for Ubuntu, but I haven't seen any on Windows. The warning is frustrating as it also appears during package installation, where it is converted into an error which is stopping the installation process.
The output for my locales is currently:
> Sys.getlocale()  "LC_COLLATE=English_Germany.65001;LC_CTYPE=C;LC_MONETARY=English_Germany.65001;LC_NUMERIC=C;LC_TIME=English_Germany.65001"
Would appreciate any help/ideas to solve the problem.
