With -psm 3, I got non-empty files (test_osd.txt) which were empty with -psm 0. This is true for both with/without -l options.
However, the results of detectOS is same for both -psm [0/3] option for any of with/without -l options. Please note that I have modified the code slightly to call detectOS separately, which has been doing a good job for orientation detection given script. I am struggling to detect the script of the input document.
