Using mathpazo only for small caps?

Question

Really simple question...

\usepackage{palatino}
\usepackage{mathpazo} <-- How can I make it alter only small caps?

Answer 1

I tried the following example:

\documentclass{article}
\usepackage{palatino}

\begin{document}

Text \textit{text \textbf{text}} \textbf{text}

\end{document}

After compiling, I ran pdffonts, getting this output

name                                 type              encoding         emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
DTGJVU+URWPalladioL-Roma             Type 1            Custom           yes yes no       4  0
LAWSFM+URWPalladioL-Ital             Type 1            Custom           yes yes no       5  0
DCSYXP+URWPalladioL-BoldItal         Type 1            Custom           yes yes no       6  0
RLNCFA+URWPalladioL-Bold             Type 1            Custom           yes yes no       7  0

The same example file with mathpazo:

\documentclass{article}
\usepackage{mathpazo}

\begin{document}

Text \textit{text \textbf{text}} \textbf{text}

\end{document}

and the output of pdffonts is

name                                 type              encoding         emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
DTGJVU+URWPalladioL-Roma             Type 1            Custom           yes yes no       4  0
LAWSFM+URWPalladioL-Ital             Type 1            Custom           yes yes no       5  0
DCSYXP+URWPalladioL-BoldItal         Type 1            Custom           yes yes no       6  0
RLNCFA+URWPalladioL-Bold             Type 1            Custom           yes yes no       7  0

As you can clearly see, the fonts are exactly the same.

So just replace

\usepackage{palatino}

with

\usepackage[sc]{mathpazo}

---

If, for some reason, you don't trust the above, use substitutefont:

\usepackage{palatino}
\usepackage{substitutefont}

\substitutefont{\encodingdefault}{\scdefault}{pplx}

On the other hand, the documentation of psnfss has

The part about mathpazo also tells you why you should prefer it to palatino:

Answer 2

You need to add new font family (pplx) to the \scshape command:

\documentclass{article}
\usepackage{kantlipsum}
\usepackage{palatino}
\pagestyle{empty}
\usepackage{etoolbox}
\pretocmd{\scshape}{\fontfamily{pplx}\selectfont}{}{}
\begin{document}
\kant[1]

\scshape\kant[2]
\end{document}

Compare to the output without this patch:
