Hi Anthony, I stumbled with the same issue for a package I submitted recently, the problem seems to be that LaTex doesn't know how to map this unicode character to a typesetting.
My unicode character was \u2229 and I tried several ways to avoid this warning. On the vignette built with knitr I declared the unicode character the following way: %\DeclareUnicodeCharacter{2229}{$\cap$} On the man pages I had to use a bit of code to print the right symbol: \ifelse{latex}{\out{$\cup$}}{\ifelse{html}{\out{∪}}{}}.} This way it passes the CRAN checks on all the machines and I didn't get any comment from the reviewer. In your case a similar changing the symbol might work, if there isn't any symbol you'll probably need to map the ligature in latex: tex.stackexchange.com/a/230140/178206. Not sure how to include that map with the package tho. Hope this helps, Lluís On Thu, 29 Oct 2020 at 15:35, Anthony Hammond <agqhamm...@gmail.com> wrote: > > Hello, > I'm attempting to upload a package to CRAN and although it passes the R CMD > checks that I run, it doesn't pass the CRAN check and the response I get is > pasted below.
