It’s trie that case mapping is quite dependent upon character sets (there’s case distinction in Latin and Cyrillic, but not in, say, Hebrew or Chinese, but it’s also dependent on language (consider the difference between turning “i” into upper case in English and in Turkish).  And comparisons in general are hard, with lots of other issues such as normalization, variants, and such (do you want 中国 and 中國 to compare as equal or not?).
