    print(line)

PDF file

Expected behavior

The vertical text in the red box should be extracted correctly.

Actual behavior

It returned unreadable text for the first row:

['Sl.\nNo.', 'District', 'noitalupoP\n31-2102\n)shkal\ndetcejorP\nnI(\nrof', '%88\not )shkal\ntludA\ntnelaviuqE\nnI(', ')yad/tluda/smg004\nnoitpmusnoC\n)sennot\ntnemeriuqer\nhkaL\nlatoT\nnI(\n@(', 'tnemeriuqeR ,sdees )egatsaw )sennot\ngnidulcnI(\nhkaL\n&\nsdeef\nlatoT\nnI(', 'Production (Rice)\n(In Lakh tonnes)', None, None, 'Surplus/Defi cit\n(In Lakh\ntonnes)', None]

And returned reversed text of the second row

[None, None, None, None, None, None, 'firahK', 'ibaR', 'latoT', 'eciR', 'yddaP']
