Hi Alex, the text is given as a HexString (correct), but the encoding of it is given by the encoding of the font referenced as the name /F1 in your PDF snippet (operator Tf). So if you'd like more information, I'd need the content of the PDF object whose reference is given after the name /F1 in the /Font property of your PDF's /ProcSet, and also the contents of the objects whose references are given after /Encoding and /FontDescriptor in that object (long arrays can be abbreviated). Thanks in advance. Pleased to read from you again. Thanks, Alex Best regards, mabri
