             Summary: Improve robustness of file extension parsing
                 Key: TIKA-4387
                 URL: https://issues.apache.org/jira/browse/TIKA-4387
             Project: Tika
          Issue Type: Task
            Reporter: Tim Allison


{{FilenameUtils.getSuffixFromPath()}} isn't checking that the extension 
contains only alphanumeric characters.

If a "file path" derives from an internal path in a pst, like so {{/Début du 
fichier de données Outlook/[WEBINAR] - "Introducing Couchbase Server 2.5"}}, 
then the extension is {{.5"}}, which causes problems on Windows.
