The following code produces an exception:

print('{:c}'.format(65536))

when executed in Idle 3.2. The stack trace:

>>> print('{:c}'.format(65536))

Seems to work fine in a terminal (Gnome-terminal in this case):

>>> print('{:c}'.format(0x10000))
𐀀

(my font doesn't have the glyph, but otherwise it works)
