Python3 error with file encodings

[GoogleCodeExporter]

What steps will reproduce the problem?
1. import fs.ftpfs
2. pfs = fs.opener.fsopendir('zip:ftp://host/path/item.zip')
3.pfs.printtree()

What is the expected output? What do you see instead?
Print zip tree, instead get:
  File "/Users/amohr/dev/drmtools/python/scripts/support/p4python/build.py", line 36, in get_openssl_dir
    pfs.printtree()
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/fs/base.py", line 1369, in printtree
    print_fs(self, max_levels=max_levels)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/fs/utils.py", line 577, in print_fs
    print_dir(fs, path)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/fs/utils.py", line 566, in print_dir
    write('%s %s' % (wrap_prefix(prefix + char_line), wrap_dirname(item)))
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/fs/utils.py", line 495, in write
    file_out.write(line.encode(file_encoding, 'replace') + b'\n')
TypeError: must be str, not bytes

What version of the product are you using? On what operating system?
0.5.0, python 3.4.1 on OSX 10.9

Please provide any additional information below.
issue is that its trying to write to stdout and it needs to be a string, and 
not a byte array.

btw another issue you'll note doing this is that the ftplib._encode method is 
encoding to a byte array when it should not be as well.
