paramiko cannot send unicode strings to stdin of applicatons

[Florian Streibelt]

The Problem occurs when doing
    data=u"mööp!"
    chan.exec_command(command)
    chan.sendall(data)

This crashes in paramiko/message.py in add_string, line 259:
        self.add_int(len(s))
        self.packet.write(s)
        return self

UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-2: ordinal not in range(128)

I guess its due to paramiko using cStringIO to internally store data.

from http://docs.python.org/2/library/stringio.html

"Unlike the StringIO module, this module is not able to accept Unicode strings that cannot be encoded as plain ASCII strings."

This leads to a problem when you want to store Unicode Strings:

import cStringIO
packet = cStringIO.StringIO()
packet.write(u"mööp!")
---------------------------------------------------------------------------
UnicodeEncodeError Traceback (most recent call last)
<ipython-input-13-4874a3de93fc> in <module>()
----> 1 packet.write(u"mööp!")

Am I missing something obvious like manually encoding the unicode to bytes?

of _course_ I was missing something after 2 days without sleep:

data= u"mööp".encode('utf-8')

works.
