When the length of the original bytes is not a multiple of 4, a special rule is used for round up. The Adobe's ASCII85 implementation is slightly different from its original in handling the last characters. The sample string is taken from: http://en.wikipedia.org/w/index.php?title=Ascii85 >>> ascii85decode(b'9jqo^BlbD-BleB1DJ+*+F(f,q') b'Man is distinguished' >>> ascii85decode(b'E,9)oF*2M7/c~>') b'pleasure.' r!uUz>Lzs~TN)structpackrange)datanboutc_s C/home/kodi/my-venv/lib/python3.13/site-packages/pdfminer/ascii85.py ascii85decoders$ IA C  7qCx FA"ad AAvv{{4++ A#X6M6 ; C #XqsA"RA$v{{4+DQqS11  J!

All white-space characters are ignored. A right angle bracket character (>) indicates EOD. Any other characters will cause an error. If the filter encounters the EOD marker after reading an odd number of hexadecimal digits, it will behave as if a 0 followed the last digit. >>> asciihexdecode(b'61 62 2e6364 65') b'ab.cde' >>> asciihexdecode(b'61 62 2e6364 657>') b'ab.cdep' >>> asciihexdecode(b'7>') b'p' latin1r) decodehex_refindallinttrail_researchappendgroupbytes)rhxrms rasciihexdecoder'9sw" ;;x D"(.."6 8"62C2J"6C 8A 3qwwqz"%*+ : 9sB__main__zpdfminer.ascii85) __doc__rer rcompile IGNORECASErr r'__name__doctestprinttestmodrrr2sl  $N OR]] 3 ::
