Answer 1

I know some people have already answered but I wanted to contribute a more holistic solution using the answer from user2554330.

# Encode data in UTF-8
for (col in colnames(DT)) {
    names(DT) <- enc2utf8(names(DT)) # Column names need to be encoded too
    DT[[col]] <- as.character(DT[[col]]) # Allows for enc2utf8() and Encoding()
    DT[[col]] <- enc2utf8(DT[[col]]) # same as users' answer
    Encoding(DT[[col]]) <- "unknown"
}

fwrite(DT, "DT.csv", bom = T)

# When re-importing your data be sure to use encoding = "UTF-8"
DT2 <- fread("DT.csv", encoding = "UTF-8") 
# DT2 should be identical to the original DT

This should work for any and all UTF-8 characters anywhere on a data.table
