FileSenderChannel with specific character encoding does not work in append mode

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create an actor that uses a FileSenderChannel
2. set the encoding to e.g. UTF-8
3. set append mode true

What is the expected output? 
- consecutive flow executions pointing to the same file should append text.

What do you see instead?
- no append mode, each run rewrites the file.

When no encoding is set, append works fine
