Nowadays, the session encoding on appropriately new versions of Windows
is UTF-8 [*]. Previously, the native encoding of the R session
corresponded to the ANSI encoding of your computer, most likely CP1252.
Let's see what does \255 mean in that encoding:

iconv('\255', 'CP1252', '') |> utf8ToInt() |> as.hexmode()
# [1] "ad"

Does '\uad' work for you?
