  Basically, it used the good ol' 8-bit LaTeX tricks to map an input
encoding to a font encoding : Unicode character -> LaTeX internal
character control sequence -> 8-bit font slot (via fontenc).  That's
what Lua saw (\T2A\CYRZ, etc.)

  Ivan, you shouldn't use fontenc at all with LuaTeX, it doesn't work.
Use luaotfload to load an OpenType font, and simply type in UTF-8.
luainputenc is useless in that case, since input is always in UTF-8.
