How to handle those is in 'Writing R Extensions': basically convert to
UTF-8 and mark them as UTF-8.

Without the actual file we can do little. The message means that
something in the manual inputs (and it could be the DESCRIPTION file or
an Rd file) contains a character not known to LaTeX. Most likely it is
simply not a UTF-8 character, but it could also be outside LaTeX's gamut.
Normally the LaTeX log (which is in the check output) is more revealing:
you can also try this part alone with R CMD Rd2pdf (and R CMD Rd2pdf
--no-description often points the finger at the DESCRIPTION file).

Assuming this is not something esoteric, UTF-8 is the most comprehensive
choice, but LaTeX's UTF-8 coverage (and that of the fonts used) is
heavily biased to Western European scripts. So for example for
Lithuanian you may want to choose something else (Latin-7?).
