In current implemetation, we use CaseFolding table from Unicode 3.1, which has
following line for these 4 letters folding,
0049; C; 0069; # LATIN CAPITAL LETTER I
....
0130; I; 0069; # LATIN CAPITAL LETTER I WITH DOT ABOVE
0131; I; 0069; # LATIN SMALL LETTER DOTLESS I
They all fold to 'i'.
In latest Unicode 4.0.1,
http://www.unicode.org/Public/UNIDATA/CaseFolding.txt
The above lines are updated,
0130; F; 0069 0307; # LATIN CAPITAL LETTER I WITH DOT ABOVE
0130; T; 0069; # LATIN CAPITAL LETTER I WITH DOT ABOVE
and Ä ('i' without dot) no longer fold to 'i'.
One way to fix this problem is to update the table we used, and we have to
maintain this table whenever it is updated.
Another way is to use icu, which provide a class to do folding. In ICU 3.2, it
uses the table from Unicode 4.0.1.
I will change the code to use icu class in next release when we update icu to
3.2.
