My LuaTeX 0.95.0 (TeX Live 2016) do not recognize command
\pdfmapfile anymore, how can I load information on fonts?
\luatexttextdir TRT is not recognized either, how can I request a different text direction?
I found no trace of the latter in the LuaTeX documentation (although by dad package developed a few years ago was heavily relying on it) and for the former it is only said that
pdf.mapfile is replacing it, does this mean that I have to switch to Lua to call a map file?
