问题 It's a tale as old as ROracle... I just can't seem to find a solution to this problem. I've uninstalled JAVA, R, and RTools and reinstalled all 3 with only 64bit versions. The build for ROracle goes fine, but I get the following error message when trying to load the package. I've looked at some of the other solutions without success and verified a 64 bit install of Oracle Client. Thoughts?

问题 I'm having issues importing norwegian characters like æ, ø, and å from an Oracle database using ROracle. I've had similar problems with RODBC before. I don't have the problem when importing from files like csv and xlsx, I'm sure the problem is with setting the encoding when importing with ROracle, but the documentation does't really tell me how to do that. Various answers write a function for converting to UTF-8 after importing, but that is not a solution that works for me. I wish to make
