Subject Re: [jira] Resolved: (PDFBOX-430) Incorrect diacritic placement in text extraction
Date Sat, 28 Feb 2009 17:26:07 GMT
Brian,

you state here that you've applied a patch by one Ken Glidden. I cannot
find any post or submission from a person with that name on the PDFBox
mailing lists. So I'm concerned about the legal trail here. Can you
explain that, please? Thank you.

much after the text chunk it overlays, but we have not observed PDF files like that.

The PDF files essentially have a chunk of text and then backup and place the diacritic over
one of the characters in the chunk of text. With text extraction, the current design does
not allow the diacritic to be placed over a character in the chunk and instead it is placed
after the chunk.
