When I try to use the tufte-book class with the adforn and pdfx packages, I am getting a problem with symbol substitutions. For example:

documentclass{tufte-book}

usepackage{adforn} 

usepackage[x-1a]{pdfx}



begin{document}

textcopyright

end{document}

Generates:

If I do any one of (a) use the article class instead (b) leave out adforn (c) leave out pdfx, I get the proper symbol:

I haven't a clue how to start diagnosing this. I could probably work around by creating my own copyright symbol, but I worry that other symbols in my large document might also be wrong. Any suggestions? Can others duplicate this?

I am using pdflatex with MiKtex on Windows.

Edit: this compiles for me without errors. Here is my logfile, I didn't see anything relevant.

The problem is common with tufte classes: they load hyperref too early. With pdfx, it is this package that should load it.

There is another small problem about tufte-book loading xcolor with options and pdfx doing the same with different options.

PassOptionsToPackage{cmyk,hyperref}{xcolor}

documentclass[nohyper]{tufte-book}

usepackage{adforn}

usepackage[x-1a]{pdfx}



begin{document}



textcopyright



end{document}

If you want to use the same hyperref setup as tufte-book, add

hypersetup{

  pdfborder = {0 0 0},

  bookmarksdepth = section,

  citecolor = DarkGreen,

  linkcolor = DarkBlue,

  urlcolor = DarkGreen,

}

before begin{document}.

Why does the issue show when adforn is loaded? It's a bug of adforn explained in https://tex.stackexchange.com/a/394388/4427. It causes the U fontencoding to be current when pdfx is loaded, so for reasons too long to be explained, L8U ends up being assigned as the default encoding for textcopyright and many other commands, which is wrong because this encoding is only for internal use.

The fix I add below might be sufficient, but it's best to use nohyper anyways.

PassOptionsToPackage{cmyk,hyperref}{xcolor}

documentclass[nohyper]{tufte-book}

usepackage{adforn}

fontencoding{T1}selectfont % work around the adforn bug



usepackage[x-1a]{pdfx}



hypersetup{

  pdfborder = {0 0 0},

  bookmarksdepth = section,

  citecolor = DarkGreen,

  linkcolor = DarkBlue,

  urlcolor = DarkGreen,

}



begin{document}



textcopyright



end{document}
