Those two characters don't have a lower/upper case mapping:

0080;<control>;Cc;0;BN;;;;;N;;;;;
0081;<control>;Cc;0;BN;;;;;N;;;;;
0082;<control>;Cc;0;BN;;;;;N;BREAK PERMITTED HERE;;;;
0083;<control>;Cc;0;BN;;;;;N;NO BREAK HERE;;;;
0084;<control>;Cc;0;BN;;;;;N;INDEX;;;;

.lower() and .upper() only modify chars which do have such a
mapping -- all others are left untouched.
