Problem: Non-ascii characters in output cause Archivematica to fail some processes

[sromkey]

Expected behaviour

If one of the tools that Archivematica uses prints out non-ascii characters, Archivematica should be able to proceed with processing and not fail the process (unless the tool itself does actually fail the process)

Current behaviour

Archivematica will fail the process if this happens, even if the tool can successfully run outside of Archivematica and complete the process.

Steps to reproduce

In a recent example, a user was attempting to normalize a PDF to PDF/a using the default Ghostscript command. Because the output included the characters >>>> Microsoft� Office Publisher 2007 <<<< , Archivematica failed the normalization job.

Your environment (version of Archivematica, operating system, other relevant details)

Archivematica 1.15.1
