[NTG-context] Forbidden things in bookmarks

Hello, The heading bookmarks don't accept some macros, like \copyright. In latex there's a handy feature that allows to define the text to put in the TOC and the text in the heading itself, like \chapter[Title in the TOC]{Actual Title in the doc}. Is it possible to do it in context? If not, maybe it could be an interesting feature to add. Example crashing if \placebookmarks used: \setupcolors[state=start] \setupinteraction[state=start] % also generate pdf bookmarks \placebookmarks [chapter,section,subsection] \startfrontmatter \completecontent \stopfrontmatter \startbodymatter \starttext \chapter{A \copyright} a a a \stopbodymatter \stoptext Regards, BG
