Does not work on Windows with Python 3: TypeError

[malversan]

Under Windows the msvcrt.getch() call returns bytes, not chars. In Python 3 both types are not compatible, so concatenating the result to a string fails with a TypeError.

This code in Platform.getkey() throws TypeError exception ALWAYS in Windows:

        buffer = ''
        for c in self.getchars(blocking):
            buffer += c
            ...

I have ammended it to work by allowing the platform classes to return bytes instead of chars:

        buffer = ''
        for c in self.getchars(blocking):
            try:
                buffer += c
            except TypeError:
                buffer += ''.join([chr(b) for b in c])
            ...

This supports any platform that captures chars, multichars, bytes or multibytes. And also complies with the Python philosophy of trying instead of checking.

Tested in:
Windows 8.1
Python 3.6.1
