[NTG-context] characters.tex.toutf bug

Hi Hans, "characters.tex.toutf" only works if there is a backslash somewhere in its input string. This leads to some really surprising behaviour in the following example: \definefontfeature[default][tlig=no, trep=no] \startbuffer[test-bib] @article{one, author = {``Author---\v{O}ne''}, } @article{two, author = {``Author---Two''}, } \stopbuffer \usebtxdataset[test-bib.buffer] \starttext \placelistofpublications[method=dataset] \stoptext Removing the following lines elseif not find(str,"\\",1,true) then return str from the definition of "characters.tex.toutf" in "char-tex.{lmt,lua}" fixes this issue for me. Thanks, -- Max
