Hi,
I'm new to the ConTeXt world and this my first post
While running the script below,
-----
\starttext
\centerdot\centerdot\centerdot
\neg\neg\neg
\stoptext
-----
I encountered the following issues with different versions of context:
* With version 1.04 (2023.07.14), the script runs successfully.
* With version 1.06 (2024.02.27), \neg is not recognized.
* With version 1.06 (2025.07.27), neither \neg nor \centerdot are recognized.
As a workaround, if I add the definitions:
\protected\def\centerdot {\Umathchar "2"0"0000B7 }
\protected\def\neg {\Umathchar "0"0"0000AC }
all three versions execute successfully.
I'm using AlmaLinux 9.6.
You could to:
\Umathchardef \centerdot "2"0"0000B7
\Umathchardef \neg "0"0"0000AC
but keep in mind that in text mode these characters are taken from the
current math font so they can look different, likely when you mix fonts,
but for instance also in a family e.g. in lucida the text one is smaller
[\centerdot] [\periodcentered]
also, we have \neg defines as a math function and there is \lnot for the
logical negation (as part of a consistency and more granular class
classification) .. see math manual
