Issue #11284 has been reported by Pablo Herrero.

----------------------------------------
Bug #11284: String#upcase and String#downcase don't work for accented characters
https://bugs.ruby-lang.org/issues/11284

* Author: Pablo Herrero
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Many accented and other non-english characters fails to upcase/downcase properly.
Accented characters is the most common are the ones I keep stumbling upon,, but probably other germanic/nordic characters I'm not aware of have the same problems.

For example:

    "Hola, ¿Cómo estás?".upcase         # returns "HOLA, ¿CóMO ESTáS?"
    "CONFIANÇA".downcase                # returns "confianÇa"
    "Un moment s'il vous plaît".upcase  # returns "UN MOMENT S'IL VOUS PLAîT"

It would be unreasonable to add natural language processing to Ruby for the sake of a few methods, and it's easy to argue the case for not doing it at all over doing it incorrectly.
