Hi Hans, \pi doesn't seem to be defined in MkIV anymore. I'm using the latest from the standalone distribution, although the issue is also present in the TL25 pretest. Minimal example:
% engine=luatex \startTEXpage \m{\pi} \stopTEXpage This was originally reported on the TeX Live list: https://tug.org/pipermail/tex-live/2025-February/051173.html Thanks, -- Max ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
