Summary: locale 1251 does not convert to upper case properly

Initial Comment:
<pre>
 # -*- coding: 1251 -*-

import locale

locale.setlocale(locale.LC_ALL, ".1251") #locale name may be Windows specific?

#-----------------------------------------------
print chr(184), chr(168)
assert  chr(255).upper() == chr(223) #OK
assert  chr(184).upper() == chr(168) #fail
#-----------------------------------------------
assert  'q'.upper() == 'Q' #OK 
assert  'ж'.upper() == 'Ж' #OK
assert  'Ж'.upper() == 'Ж' #OK
assert  'я'.upper() == 'Я' #OK
assert  u'ё'.upper() == u'Ё' #OK (locale independent)
assert  'ё'.upper() == 'Ё' #fail
</pre>

I suppose incorrect realization of uppercase like 

<pre>
if ('a' <= c && c <= 'я')
  return c+'Я'-'я'
</pre>

symbol 'ё' (184 in cp1251) is not in range 'a'-'я'
