The string "\u0327\u0043" does not normalize to the same string as "\u00C7", as combining characters are supposed to _follow_ the base character. (Some consoles may happen to display them the same way, but prepend another letter to the string and it's clear that the combining cedilla is attached to that and not to the C.)

Switching the two escape sequences makes the example work. Patch attached.
