Research direction

Start with org.apache.ftpserver.listener.nio.FtpResponseEncoder.encode at FtpResponseEncoder.java:49 and the OPTS_UTF8 path at OPTS_UTF8.java:54, then trace the response written through Apache MINA. Reproduce the CharsetEncoder failure and identify the cause; done means the reported crash no longer occurs and the affected path has coverage.
