Hi Mike#1 and George,

1. What do you think of using toUtf8() instead? I am hoping that will
fix the bug regardless of the locale.

I tried changing it to that (bug566.utf8.test.patch), but it still did
not fix this bug with the greek username on my system with the locale
set to English. It did not introduce a regression for my ASCII user
account at least.

If libssh needs to be recompiled for Unicode, I can do that. I just
recompiled it for bug #590.

FYI: This is the API we are calling:
http://api.libssh.org/stable/group__libssh__session.html#ga7a801b85800baa3f4e16f5b47db0a73d

2. in sshmasterconnection.cpp, we also set "SSH_OPTIONS_USER" . I
think that we should also change its value from to.Ascii() to
toLocal8Bit() or toUtf8(). bug566.test.v2.patch has this change for
toLocal8Bit(), and bug566.utf8.test.patch has it for toUtf8().
