Issues771 - Fixing windows Unicode Errors

[allmightyspiff]

slcli image list --public has a unicode character that causes an exception in Windows shells for some reason.

image id=1288413 is the problematic one. To reproduce on master

$ ./slcli image detail 1288413
An unexpected error has occured:

Feel free to report this error as it is likely a bug:
    https://github.com/softlayer/softlayer-python/issues
The following snippet should be able to reproduce the error
(py36)


$ ./slcli image list | grep 1288413
(py36)

When fixed should look like this:

$ ./slcli image detail 1288413
UnicodeEncodeError detected, printing as JSON.
