[R] "found 4 marked UTF-8 strings" during check of package... but where !

[Marc Girondot]

Thanks Duncan and Michael,

Indeed I have data file with utf-8 characters inside. In the 
DESCRIPTION, I have the line Encoding: UTF-8
but it seems to not be sufficient.
In each R page for these data, I have also :
#' @docType data
#' @encoding UTF-8

But I still have the notes during check when I try to submit the package 
in CRAN (not in local --as-cran check).

How I could "say" that these data have utf-8 characters inside?

Thanks
Marc
