Hello, Ivan et al.:
I tried escaping "%" every time it occurred without success, but
adding "\encoding{UTF-8}" as the 4th line of nuclearWeaponStates.Rd
eliminated that problem.
Sadly, I tried "R CMD build --resave-data=best Ecdat", "R CMD
build --resave-data Ecdat", "R CMD build Ecdat --resave-data", and "R
CMD build Ecdat --resave-data=best", all without success. I also noted
that .travis.yml contains "r_build_args: --resave-data", which I
remember adding some time ago to fix this problem. And Travis reported
this problem as well. This suggests to me that a change was introduced
with R 4.0.0 that disabled this option.
I also tried loading and resaving all the files in the data
directory. This seemed to achieve some additional compression on
average, but I still got, "Note: significantly better compression could
be obtained by using "R CMD build --resave-data". I then tried load and
saveRDS on each one individually, but at least the first of the
resulting *.rda files was corrupted, so I restored what I had before.
Anyway, Ivan's suggestion fixed the UTF-8 problem and Travis
confirmed that it can't make "--resave-data" work, either ;-) If a CRAN
maintainer complains about the compression problem, I can report what I
tried and see what they suggest.
Thanks again,
Spencer Graves

However, if I use this inside "\href", "R CMD check" doesn't
recognize the close curly bracket because of the presence of the
non-ASCII characters.
WRE section 2.3 [*] provides an example of \href with RFC3986
percent-encoding. Since % is a comment character in Rd, the percent
signs have to be escaped with backslashes:
\href{https://www.americansecurityproject.org/ASP\%20Reports/Ref\%200072\%20-\%20North\%20Korea\%E2\%80\%99s\%20Nuclear\%20Program\%20.pdf}{Derek
Bolton (2012) North Korea's Nuclear Program}
This only works correctly in R >= 3.1.3, but results in correct output
in both HTML and PDF formats.
Alternatively, it should be possible to declare the encoding of the Rd
file using \encoding{UTF-8} (WRE 2.14 [**]), but in my tests (R 3.6.3,
could have been fixed in later versions) it results in a broken link in
Rd2pdf output.
I'm getting, " Note: significantly better compression could be
obtained by using R CMD build --resave-data". I get this message
even though I use "R CMD build --data-compress Ecdat". I also tried
"R CMD build Ecdat --data-compress" and got the same result.
The note offers you to try adding --resave-data to R CMD build, not
--data-compress. What happens if you use --resave-data=best?
--data-compress doesn't seem to be an R CMD build option; at least
it's not mentioned in R CMD build --help.
WRE 1.1.6 [***] provides an example of --data-compress as an option of
R CMD INSTALL (not build).
