Ken Krugler commented on TIKA-1002:
-----------------------------------
The issue is that the JRE doesn't support UTF-7. See
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4304013 for details.
Also Unicode-1-1-utf-7 is supposedly obsolete - the sender should be using
UTF-7.
Finally, this is an upstream issue, as the error is being thrown by POI. So we
couldn't fix it in Tika even if we wanted to, unfortunately.
