Greek text in multi-language document becomes invalid, when attempt to edit document

[MustardTrout]

I am editing a book to be published on Ancient Greek inscriptions. The document contains Russian, English and Greek (Hellenica font) texts, as well as pictures. Whenever I try to make any changes whatsoever to any part of the document, the Greek text somehow changes and becomes invalid (it still contains Greek characters, but they are all out of order). Would greatly appreciate help!

You should not be editing the PDF files directly. PDF should be the "final

format" in your workflow.

If edits are needed use the commenting tool to mark them up and then send

the file back to the author and ask them to implement them in the original

file format and then produce a new PDF.

Thank you very much for your reply! If I can't edit PDFs directly, then there is no point in purchasing Acrobat DC Pro. After a 1000-page book was converted by the maker-up to PDF format, having introduced ample changes to the Books' lay out -- editing the old version of the original text is inexpedient, while converting the book back to the original Word format (we have tried it) results in the loss of the Greek text and substantial typographic losses.

You can edit PDF files directly, but you shouldn't, exactly for the reasons you've encountered.

If you deleted the original file used to create this book then you have a serious problem. You can try to export the PDF back to Word and then edit it, but the results might be less than satisfactory.

The bottom line is that Acrobat can edit PDF files, at a pinch, but it should be avoided if at all possible, and you must always keep a copy of the original file used to create a PDF in case any edits are required. Any publishing house should know that.

Thank you for your concern! We have numerous copies of the original Word file, but it is very different from the makeup we have received in PDF. I now understand that Acrobat should NOT be used for major or minor edits, since even minor edits may affect the whole document, resulting in numerous errors throughout the document and that I need to contact the publishing house for help. Thank you!
