1) Do you know that converting PDF to text (regardless of lua) is only 
possible if it especially contains that source text (which is not always the 
case)?
2) as far as I know, there is no such module not only for lua, but for all of 
script languages I know.
3) unlike the reverse operation. There is some for text->pdf
4) anyway, the purpose of PDF is *not* to provide capability to get text back. 
It is to make document looks similary everywhere (like it was printed on the 
paper).
