Then you are wrong in your expectation.
We (other low level users) might expect that R CMD check warns or better
fails when a documentation file has not been edited so that it contains
sensible information. It is alreeady constrructed for you. So just edit
it and replace the parts by relevant information that R cannot fill in
for you. Please read the manuals and the readme file provided....

Then you have to declare an encoding as the manual "Writing R
Extensions" suggests.
