Thank you for a very detailed report!
This doesn't happen on R-4.2.2 or 4.3.1, but it does happen on R-devel.
Comparing the calls from R CMD check to R CMD Rd2pdf, I see no
difference in the environment variables or any significant difference
in the command lines. The command being run ends up being equivalent to
R CMD Rd2pdf <package>.Rcheck/<package>
...and the source of the difference is the presence (or absence) of the
<package>.Rcheck/<package>/latex directory. If I temporarily move it
away during an R CMD check --install-args=--latex run, the command
succeeds.
Indeed, tools:::.pkg2tex says
>> ## First check for a latex dir (from R CMD INSTALL --latex).

The individual *.tex files in the latex/ subdirectory of the installed
package all do start with an "\inputencoding{utf8}" line.
When the latex/ subdirectory doesn't exist, the !dir.exists(latexdir)
branch is taken, where Rd2latex(...) is called with writeEncoding =
FALSE, thus avoiding the problem.
