Description

When parsing a file with messed up encoding flume spits this error:

23 May 2013 22:06:29,446 ERROR [pool-12-thread-1] (org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run:164) - Uncaught exception in Runnable

It would be good to skip such characters, ignore them or delete. Corrupt signs come from spamming engines, flume cant handle them at all.
