It doesn't seem to be that:

$ pdffonts a6.pdf
name                                 type              encoding         emb sub uni object ID

It seems it is compiled with LuaTeX:

$ pdfinfo a6.pdf

When I try that I get:

$ context --luatex a6lua.tex 
mtx-context     | redirect luametatex -> luatex: luatex --luaonly "/mnt/tex/tex/texmf-linux-64/bin/mtxrun.lua" --script mtx-context --luatex a6lua.tex --redirected
mtxrun          | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'

I didn't know any of the poppler-utils, thank you!
