I am using Arch Linux. I install TeXLive via system's package manager pacman (the packages installed will be listed later):

If I compile the following code

\documentclass{minimal}

\newcommand{\printinternalcurrentfont}{%
  \expandafter\texttt\expandafter{\expandafter\string\the\font}%
}
\newcommand{\printexternalcurrentfont}{%
  \expandafter\texttt\expandafter{\fontname\font}%
}


\begin{document}


\printinternalcurrentfont


\printexternalcurrentfont


``test''


\end{document}

by xelatex, it prints

\TU/lmr/m/n/10

"[lmroman10-regular]:mapping=tex-text;" at 10.0pt

``test''

and if it is by pdflatex, it prints:

\OT1/cmr/m/n/10

cmr10

“test”

Notice the difference:

  1. They use different fonts: for PDFLaTeX, it use cmr (Computer Modern Roman, I guess?), and
  2. The ligature in the XeLaTeX case is not enabled (without any setups for fonts)

I want to know if this is a matter of the environment, so here is the list of the installed TeXLive packages (from output pacman -Qs texlive):

    xelatex should give this output in an up to date texlive – David Carlisle Jan 27 '24 at 12:37
  • what are you showing in your question it appears to be text. Do you mean you cut and pasted from the pdf output? (the results of cut and paste always depend on the pdf viewer) what does your output image look like, see my above comment – David Carlisle Jan 27 '24 at 12:39

  • @DavidCarlisle Yes, I cut and pasted from the PDF output. Since the texts I pasted here looks the same as the PDF output, I did not bother to make a screenshot. I did not get your output with my texlive (which should be up-to-date). The question has been labeled as a duplicate and thank Ulrike Fischer for pointing out the solution! – Hoyan Mok Jan 27 '24 at 15:41
