Copying from pdf worked for me. At least, there was no gibberish,
although the indentation was lost.

I used Foxit Reader on Windows, pasting to an Emacs buffer:

-- defines a factorial function
function fact (n)
if n == 0 then
return 1
return n * fact(n-1)
print("enter a number:")
a ="*n") -- reads a number

It might not be deliberate obfuscation, but an incompatibility between
the pdf generator and reader software.
