This doesn’t work when you have more than one paragraph in the Citation environment.26. Oktober 2016 um 16:30after some readings in the TeX book I came up with the following solution that works for me without having to change all my instances of startstopCitation in the text.
Here is a alternative version but you need a empty line or \par after \stopCitation.\definestartstop
[Citation]
[
before={\hangindent=20mm\hangafter=0\symbol[leftquotation]},
after={\removeunwantedspaces\symbol[rightquotation]},
]
\starttext
\startCitation
\input tufte
\stopCitation
\footnote{This is a Quote of Donald Knuth}
\input tufte
\stoptext
