I released my first R package several days ago. The section on binary builds in R Packages says that one should inspect the check results for the package after some days.
Some of the results report a note with the text "found 6034 marked UTF-8 strings". What does that mean? Is there something wrong with my package? Do I have to do something, e.g., to prepare a patch?
Since it's on to CRAN, that means the CRAN admins were ok with it. And since CRAN is stricter/more nit-picky than most R users will be, you should be fine.
