[NTG-context] luatex 0.74: invalid escape sequence near '\%

Hi, luatex 0.74.0 has problems with an escaped string which used to work in 0.72. Small example (typeset git information, so may only work in directory under version control): \starttext git revision \ctxlua{context(os.resultof("git --no-pager log --pretty='\%h of \%aD' -1"))} \crlf ConTeXt version: \contextversion] \stoptext I get ! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\%'. system > tex > error on line 3 in file test.tex: LuaTeX error ... All best Thomas
