[R-pkg-devel] checking PDF version of manual without hyperrefs or index ... ERROR

[Lluís Revilla]

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
