I'm using the libertinus font in order to match the math to my text (i used linux libertine). I need a \mathcal{L} symbol in my text, but i'm only getting a regular L. I looked at the documentation of the font and compiled the .tex document myself. I get a different output, however. Here is a passage using \mathcal{A} in the uploaded pdf-file: Image of uploaded pdf

here is an image of the same passage in the document i compiled myself: Image of self-compiled document

As you can see, there is clearly a difference.

I'm confused. I wanted to find a difference in my preamble to the documentation, but even the documentation (using the exact same .tex file) gives me different results. I have no idea how to fix this, i don't know much about font handling. Note that this could be my only issue, so having a special treatment of \mathcal{L} would be fine (though i would love to learn more about the difference here).

Here is a MWE taken from the linked .tex file:


\setmainfont{Libertinus Serif}
\setsansfont{Libertinus Sans}
\setmathfont[AutoFakeBold]{Libertinus Math}



%    Enclose the argument in vert-bar delimiters:

    Let $\A$ be an arrangement. Then
    \[ \chi (\A,t) = \sum_{\BB \subseteq \A}
    (-1)^{\abs{\BB}} t^{\dim T(\BB)}. \]
  • Why not adding the .tex file here? I don't like following external links just to fetch some code... – user31729 Jan 25 '17 at 16:38
  • Sorry, i added a MWE. I took the documentation file an stripped everything not needed. – pschulz Jan 25 '17 at 16:51
  • I've used your MWE and I get the output you have shown in the first image, i.e. the desired one – user31729 Jan 25 '17 at 16:54
  • Hm, this is strange. Unfortunately, adding \usepackage[libertine]{newtxmath} didn't help. – pschulz Jan 25 '17 at 16:58
  • My suggestion was an error. I confused libertine with libertinus. I've removed my comment – user31729 Jan 25 '17 at 16:59

The font on CTAN seems to be faulty. You need to download the newest version from github https://github.com/khaledhosny/libertinus/blob/master/libertinusmath-regular.otf and either replace your font or move it e.g. to your current folder and load it with

    And, if using LuaTeX, you might need to refresh luatex-cache when you replace an existing font file with a newer version. – user103221 Jan 25 '17 at 18:59
