[NTG-context] Wrong ToUnicode table for ZapfDingbats font

Hi, Consider the following MWE, that displays a ZapfDingbats check mark: \definefontsynonym[ZapfDingbats][file:ZapfDingbats][features=dingbats] \definefont[zapfdingbats][ZapfDingbats] \starttext \getnamedglyphdirect{ZapfDingbats*dingbats}{a19} \stoptext In earlier versions, e.g., 2016.03.13, the font in the PDF contains a correct ToUnicode table with: ... 1 beginbfchar <0013> <2713> endbfchar ... In the currently newest version, 2016.06.08, the ToUnicode table lacks the entry for the check mark: ... 0 beginbfchar endbfchar ... Hence, the check mark cannot be copy pasted from the PDF. I fear this may be a bug. Or am I missing something? Any feedback is welcome. Christoph
