Message2822

Actually I spoke too soon, there's one issue -- this patch will break formatting unicode chars with values larger than 255:

Jython 2.3a0 on java1.5.0_07
Type "copyright", "credits" or "license" for more information.
>>> u'%c' % 256
Traceback (innermost last):
  File "<console>", line 1, in ?
OverflowError: unsigned byte integer is greater than maximum

Without the patch jython *appears* to handle these values as CPython does, but I suspect there may be more involved, as the exception raised by CPython when the unicode formatting fails seems to suggest that CPython runs the value through something similar to unichr():

Python 2.4.4 (#1, Aug 19 2007, 19:54:52)

>>> u'%c' % 256
u'\u0100'
>>> u'%c' % -1
