Avoid problems in str.format() with char accents

[davizucon]

If you input a char like "é" or "ã" with terminalAdapter, in log method str.format(), if no unicode .format(() raise a error.

To reproduce, just clone master, and run with IN/OUT using TerminalAdapter.

Thanks

Hi @davizucon, sorry about the delay in reviewing this. I was able to confirm the issue, but I'm going to have to make a small change to the pull request so that it doesn't break Python 3 compatibility.

Python 3 has an improved way of dealing with strings which eliminates issues with unicode characters, however it breaks backwards compatibility with the string decode method.

Python 3:

'é'.decode('utf-8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'decode'

Python 2.7:

'é'.decode('utf-8')

>>> u'\xe9'
