@DavidCarlisle you are not mean :)

@cfr awww thank you

@Rmano ooh thanks mr. squirrel!

@DavidCarlisle oh no

10 hours later…

I wonder why this gives a warning with lualatex for a font that's not used at all?

\documentclass{article}
\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella}
\usepackage{tikz}
\begin{document}
\tikz \node[font=\fontsize{13}{15}\selectfont]
    { \begin{tabular}{l}X\end{tabular} };
\end{document}

@yo' math mode is used in tabular and tikz in various places, and you are seeing the math fonts being set up badly at 13pt

@yo' we probably should do this anyway for luatex it makes no sense having legacy bitmap sizes in luatex

\RequirePackage{fix-cm}
\documentclass{article}
\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella}
\usepackage{tikz}
\begin{document}
\tikz \node[font=\fontsize{13}{15}\selectfont]
{ \begin{tabular}{l}X\end{tabular} };
\end{document}

yo'

@DavidCarlisle \RequirePackage{fix-cm} was what I missed! Thanks a lot!

But it's a funny issue at best :)

David Carlisle

@yo' we really shouldn't make you explictly tweak 7 bit font support in an apparently Unicode document...

yo'

@DavidCarlisle I won't argue with that point ;-)

So the problem would be also solved by loading unicode-math?

David Carlisle

@yo' yes

yo'

cool. That sounds cleaner in a sense... (even though it means loading a myriad of never used code!)

David Carlisle

@yo' I'll ~~blame @UlrikeFischer~~ raise with the team

yo'

Thanks!

David Carlisle

of course it's all pointless anyway as math is just used to get hold of \vcenter so it doesn't need the fonts at all (just a setting for the math axis height)

Ulrike Fischer

@DavidCarlisle hm, I though we do not use vcenter with array but it loads math anyway?

@DavidCarlisle ah, no there is still a \vcenter.

David Carlisle

@UlrikeFischer you have mail (team:-)

Skillmon

@DavidCarlisle should finally do the switch to drop \vcenter.

David Carlisle

20:56

@yo' done

@Skillmon we have code to do that but it's not entirely trivial not breaking stuff, probably will do it as part of tagging if \DocumentMetadata is used as the hidden math is a pain there for other reasons

Skillmon

I guess if Knuth didn't implement \vcenter as centred on the math axis, it would most likely be aligned to the baseline of the middle line, and on even lines the verticle centre of the baselines of the two most middle lines. Because alignment was never meant to be straight forward :)
