Lua: Input formats which don't work with pandoc.read (binary, zip etc.)

[bpj]

Where can I find a list of input formats which don't work with pandoc.read in Lua? I assume this will be those formats whose files are binary/zip, bibliographies etc., but I'm not quite sure which those are.

Ok answering myself: all formats occurring as keys in pandoc.readers work. I should have known that!
