LaTeX forum ⇒ Fonts & Character Sets ⇒ Specifications for Math Numerals

[hugovdberg]

I use mathspec to change the numerals from eulervm to the numerals from my text font, which do blend quite nicely. I have to this because I also use siunitx, and no matter what setting I use, in math mode it will use the euler numerals even if I don't set the euler-digits option. Unfortunately, with the \setmathfont also the digits within the DOI identifiers in my bibliography are changed, and thus look really ugly. I tried using and explicit \setmonofont, that does change the letters and symbols, but still not the digits, whether I set the mono-spaced font before the math font or after it. Also note I only set the FreeMono as mono-spaced font for extra contrast to see what changed, I think it's rather ugly and definitely prefer a font better fitting with the rest of the text.

Below are the files "test2.tex", and "test2.bib" (sorry, "test.tex" was already actively in use ) I also attached the corresponding output on my system.

A small update on the issue, for now I just set my monofont to Calluna, since in the current document I don't need listings or verbatim environments. However, if someone could point me in the right direction where to find the declarations that specify the typesetting of the DOI I would be very grateful.

Since apparently nobody over here can help me I decided to cross-post it to TeX.sx, see my question over there: http://tex.stackexchange.com/questions/ ... references

Thanks to egreg at TeX.se this problem has been solved, the code below is his solution to the problem.

Another update of this topic, since it later turned out this didn't solve the problem entirely. This solution works as it stands with TeX Gyre since that has lining figures as its default numerals (so named characters one, two, three, etc. for those familiar with OpenType fonts' internals), but Calluna, and the more regularly available EB Garamond have OldStyle figures by default. These are not loaded correctly without adding the option Renderer=Basic to the \liningmain font specification, but then the font is loaded correctly only about half the time, randomly changing between compilation runs. At the moment we suspect this is caused by a bug in luaotfload, so an issue has been opened at their GitHub, hopefully a fix will be available any time soon.
