Didn't know this :-) Now I remember that even for German there exists
"ß" which has no capitalisation. Some people use "SS" or "SZ" or even
"ß" for it. Don't know what toupper("ß") returns.

So converting a string containing "ß" to upper case could result in some
false negatives too :-)
Nevertheless I'm sure that just a funny example. In praxis it will not
cause harm.
