[NTG-context] Footnote mark gap

Dear All, when footnotes are placed after certain accented characters, the corresponding footnote marks are rendered too close to them: \starttext í\footnote{í} T\footnote{T} ľ\footnote{ľ} ě\footnote{ě} ď\footnote{ď} \stoptext Is there any option for making this distance a bit larger? On the other hand this gap may produce too much white space when placed after characters like period or comma... Ideally it could be positioned 'optically' ;-) Regards, Jan
