The OP kind of alluded to that: there is no such thing really as 
language-independent character folding.

About the closest approximation you can get using Unicode data alone 
(not CLDR) is to normalize to NFD, then ignore the combining diacritics. 
But that still doesn't work for a character like ø, which doesn't 
decompose to o + anything, and more importantly, it still won't meet 
expectations because of the n/ñ and o/ö/ø language-dependency problems.

As Mark and Philippe said, the real solution is to use CLDR, because 
that is where language-dependent information like this lives.
