Multiple and inconsistent error messages
I am getting errors and warnings such as:
Error: UnknownErrorException: bad XRef entry Warning: Ignoring invalid character "116" in hex string
When parsing succeeds, the resulting text seems to differ from one trial to the next.
The diagnostics don’t tell, in terms I can understand, me what the problems are and how to solve them.
This is happening on multiple PDF files that ordinary viewers open.
