No, the problem has nothing to do with character sets, but with the actual alphabet that humans in Turkey use, which doesn't follow the same rules as the alphabet that American humans use. Unicode (the standard, not the character set or any of its encodings) has an algorithm / lookup table for "case folding", because "convert everything to lower case" is not a reliable way to produce case insensitive comparisons. Using that correctly world presumably solve this particular problem. The bottom line is that case sensitive comparisons are easier than case insensitive ones. Early programming languages and OSes just ignored the edge cases (or ignored the existence of the world outside the USA altogether), some later ones decided the whole thing wasn't worth the effort.
