Re: Capital K as operator like \sum

Yes, I forgot about your existing companion fonts.  Attached is the merged
companion font and the adjusted .lfg file.   I have no idea what is a
sensible unicode point so I just used E1200.

@Matthias: Putting these two files in the right place on your system should
work (likely the same place as your .tex file is sufficient)

\setupbodyfont[pagella]
\starttext
\definemathoperator [kb] [sum] [left="E1200]
\starttext
\m{\kb_{i=1}^\infty \neq \sum_{i=1}^{\infty} i^{-1}=1}
\startformula
\kb_{i=1}^\infty  \frac1i \ne \sum_{i=1}^\infty \frac1i =1
\stopformula
\stoptext

@Matthias: Hans put Pennstander into ConTeXt so if you have an updated
version then \setupbodyfont[pennstander] should just work.   Newer versions
of the font might be the ones on github.
