Latin Modern main font with bold small capitals from CMU Serif

Question

I want to use bold small capitals from CMU Serif while setting Latin Modern as my main font.

Minimal working example

\documentclass{report}
\usepackage{mathspec}
\setmainfont{Latin Modern Roman 10 Regular}[
    BoldFeatures = {SmallCapsFont = {CMU Serif Bold}},
    SmallCapsFont = Latin Modern Roman Caps]
\begin{document}
Roman. \textbf{Bold.} \textsc{Small capitals.} 
\textbf{\textsc{Bold small capitals.}}
\end{document}

Output

Errors

How can I resolve these errors? Bold small capitals from CMU Serif work fine when I'm not using fontspec.

Edit. Maybe I can adapt this answer? I know how to do import a symbol from mathabx but not from CMU Serif. I will just be using bold small capitals for heading numbers, so it doesn't matter if I have to define new symbols.

You might have a look at New Computer Modern. – Davislor Oct 24 '20 at 20:17 — Davislor, Oct 24 '20 at 20:17
Add SmallCapsFeatures={Letters=SmallCaps}. – Ulrike Fischer Oct 24 '20 at 20:17 — Ulrike Fischer, Oct 24 '20 at 20:17

As Ulrike Fischer said in her comment, you’re correctly selecting the small caps font but need to also select its small-caps feature. You also need a few more lines to enable slanted small caps.

\documentclass{report}
\usepackage{fontspec}
\setmainfont{Latin Modern Roman}[
  SmallCapsFont = Latin Modern Roman Caps,
  UprightFeatures = {SmallCapsFeatures = {}}, % Suppresses warning about missing smcp feature.
  BoldFeatures = {SmallCapsFont = {CMU Serif Bold}},
  ItalicFeatures = {SmallCapsFont = {CMU Serif Roman Slanted}},
  BoldItalicFeatures = {SmallCapsFont = {CMU Serif Bold Slanted}},
  SmallCapsFeatures={Letters=SmallCaps}]
\begin{document}
    Roman font. \textbf{Bold font.} 
    \textsc{Small caps font.} \textbf{\textsc{Bold small caps font.}}
\itshape Italic font. \textbf{Bold font.} 
\textsc{Small caps font.} \textbf{\textsc{Bold small caps font.}}

\end{document}

You might also try New Computer Modern, which redesigned its small caps.

It didn't work for me. See update. – simple jack Oct 24 '20 at 20:38

@simplejack The warning you’re getting about Latin Modern Roman Caps lacking the scmp OpenType feature is harmless. You can, however, suppress it by moving the SmallCapsFeatures={Letters=SmallCaps} option within the BoldFeatures, ItalicFeatures and BoldItalicFeatures blocks. – Davislor Oct 24 '20 at 21:05
@simplejack I edited in a fix to suppress the warnings. – Davislor Oct 24 '20 at 21:08
The issue is that the output doesn't have bold small caps ... – simple jack Oct 24 '20 at 21:12
@simplejack It does on TeX Live 2020. – Davislor Oct 24 '20 at 21:31
I'm using TeXShop so I don't see why it would be any different. – simple jack Oct 24 '20 at 22:12
Are you getting any error messages about missing fonts in your .log? – Davislor Oct 24 '20 at 23:36
The fienames (cmunrm.otf for CMU Serif, cmunbx.otf for CMU Bold Extended, cmunbl.otf, for CMU Unicode Bold Slanted, and cmunsl.otf for CMU Unicode Slanted) might work. – Davislor Oct 24 '20 at 23:38
When I implement this solution, I find that \textsl{...} becomes identical to \textit{...}. Is this the expected behavior? – LaTeXereXeTaL Oct 30 '20 at 21:54
@LaTeXereXeTaL Very few font families have separate \itshape and \slshape faces. – Davislor Oct 30 '20 at 22:11
My question still isn't resolved... I gave it to you to say thanks for trying. – simple jack Jan 06 '21 at 13:07
@simplejack Thank you. but I’m confused when you say you aren’t getting bold small caps. As you can see in the image, this does produce bold small caps and bold italic small caps for me, on TeX Live 2020. Are you using another TeX distribution? – Davislor Jan 06 '21 at 17:18
@Davislor I'm not sure why it doesn't work or why I get that error message. I'm using MacTeX 2020. – simple jack Jan 14 '21 at 21:32
