Answer 1

It might be easier to use the stringi package. This way, you don't need to check the encoding beforehand. Furthermore stringi is consistent across operating systems and inconv is not.

library(stringi)

base <- data.table(terme = c("Millésime", 
                             "boulangère", 
                             "üéâäàåçêëèïîì"))

base[, terme := stri_trans_general(str = terme, 
                                   id = "Latin-ASCII")]

> base
           terme
1:     Millesime
2:    boulangere
3: ueaaaaceeeiii
