msvcrt function calls need to be renamed to unicode equivalents, because now they return bytes, which doesn't support string methods used to process the output (e.g. lower()).
http://docs.python.org/py3k/library/msvcrt.html
msvcrt.getch() -> msvcrt.getwch()
msvcrt.getche() -> msvcrt.getwche()
msvcrt.putch() -> msvcrt.putwch()
msvcrt.ungetch() -> msvcrt.ungetwch()

The original function names are still listed and the wide versions have been added to the docs so this can be closed as "out of date".

The bytes type has supported string methods for a long time now. I don't think there's anything else to do here. msvcrt.getch() is a low-level I/O function like os.read(). It should not be automatically converted to msvcrt.getwch(). Unfortunately the function names weren't changed in Python 3. I'd rather that msvcrt.getch() returned str and msvcrt.getchb() returned bytes. Then there would have actually been something for 2to3 to convert (e.g. getch -> getchb, and getwch -> getch).
