问题
I am using the ROracle library to access an Oracle database from RStudio. Please see the code below:
drv = dbDriver("Oracle")
connect.string = paste(
"(DESCRIPTION=",
"(ADDRESS=(PROTOCOL=tcp)(HOST=", host, ")(PORT=", port, "))",
"(CONNECT_DATA=(SID=", sid, ")))", sep = "")
con = dbConnect(drv, username = "",
password = "",dbname=connect.string, encoding="latin1")
### Pull tables
keyword = dbGetQuery(con, "select COLUMN1,COLUMN2 from TABLE1")
In my column i got the words: Lørdag, søndag etc which is returned as: L?rdag, S?ndag.

Finally works! Apparently i couldnt find any way to force encoding in my code. However, i added the environment variable "NLS_LANG" and the corresponding langauge code to my operating system which fixed the issue
