I'm trying to fiddle TeX Gyre Heros' Small caps into Helvetica using fontspec and xelatex; here's an MWE of my code:

\usepackage{fontspec} %v2.5a

%\setmainfont{texgyreheros-bold.otf} % this works
%\setmainfont{Helvetica} % this also works
\setmainfont{Helvetica}[BoldFeatures = { SmallCapsFont = {texgyreheros-bold.otf} }] % this does not work

As you can see be the comments, both Helvetica and TeX Gyre Heros alone work fine. However, if I try to specify TeX Gyre Heros as Bold/Small caps font for Helvetica I get the following error:

                                                   % this does not work

Can I intermix Helvetica and TeX Gyre Heros using fontspec (this way)? If not, why? (I have no clue what is happening, but I'd like to get some understanding to avoid pitfalls in the future.)

If I'm missing any important information, let me know.

Thanks for your time.

It seems that mixing renderers is not accepted by fontspec:

\usepackage{fontspec} %v2.5a

  BoldFeatures = {
    SmallCapsFont = {TeX Gyre Heros/B},
  SmallCapsFeatures = {
] % this does not work

\setsansfont{TeX Gyre Heros}


\sffamily % as a check

  • What do you mean by "missing renderers"? That the options is not set? Or that it is not available on the system? Because I have another document where I had to set Renderer = AATby hand to get small caps from Hoefler Text. So I think AAT-Renderer is available on my system. Commented Jul 27, 2016 at 13:22
