I am preparing a package where I would like to use UTF characters in .Rd
files. When the LaTeX comes to play, I got well known errors e.g.:
! Package inputenc Error: Unicode character ∂ (U+2202)
(inputenc) not set up for use with LaTeX.
It is coherent with what is said on this page
"Since LaTeX cannot handle Unicode we would have to convert the encoding
of latex help files or use Lambda (and tell it they were in UTF-8)."
But LaTeX can support UTF8 as shown with this small example:
The vorticity ω is defined as $ω = ∇ × u$.
I can compile it with my LaTeX without problem. May be you too?
So my suggestion would be to place these two lines somewhere in LaTeX
header generated by R doc system:
Note "utf8x" and not just "utf8" which is crucial for this example.
With a hope that it would fix unicode errors from LaTeX.
