Hello I have found that trep=yes gives me correct closing quotation marks in the commercial font Baskerville MT Pro if I type the simple ' as usual in TeX; but opening quotation marks remain as ` or ``. In XeTeX I could get round this with e.g.: \catcode"0060=\active% 0060 is the position for ` \def`{{\char"2018}}% 2018 is the position for ‘ (opening quote) But this fails in ConTexT. Any idea how to fix this, with or without any \catcode fiddling? (In XeTeX the font works as expected if I just give mapping=tex-text when setting up the font call, but I don't see an obvious version of that in ConTexT.)
