In the following case, the bind does not work:
x <- data.table(A = 1, B = 2, C = 3)
y <- copy(x)
setnames(x , c("Ä", "Ö", "Ü"))
setnames(y , iconv(c("Ä", "Ö", "Ü"), from = "UTF-8", to = "latin1"))
Encoding(names(x))
Encoding(names(y))
rbind(x,y)Output:
[1] "UTF-8" "UTF-8" "UTF-8"
[1] "latin1" "latin1" "latin1"
Error in rbindlist(l, use.names, fill, idcol) (rbindbug.R#7): Column 1 ['Ä'] of item 2 is missing in item 1. Use fill=TRUE to fill with NA (NULL for list columns), or use.names=FALSE to ignore column names.
