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. róó!óuééUé!éz>Lózsó~éTN)ÚiterÚbytesÚordÚstructÚpackÚstrÚrange)rÚnÚbÚoutÚiÚcÚ_©rúI/home/ubuntu/webapp/venv/lib/python3.10/site-packages/pdfminer/ascii85.pyÚ ascii85decode s.   € úrs ([a-f\d]{2})s#^(?:[a-f\d]{2}|\s)*([a-f\d])[\s>]*$cCsZdtdtfdd„}d}t |¡D]}|||ƒ7}qt |¡}|r+||| d¡dƒ7}|S)aæ ASCIIHexDecode filter: PDFReference v1.4 section 3.3.1 For each pair of ASCII hexadecimal digits (0-9 and A-F or a-f), the ASCIIHexDecode filter produces one byte of binary data. 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.
