Hi.

For unknown characters, the following may be useful

  x <- "n/a "

  library(Unicode)
  u_char_inspect(as.u_char_seq(x, ""))

      Code                 Name Char
  1 U+006E LATIN SMALL LETTER N    n
  2 U+002F              SOLIDUS    /
  3 U+0061 LATIN SMALL LETTER A    a
  4 U+00A0       NO-BREAK SPACE
