> Another example is Turkish, where there are two capital I's, one with a dot, one without. It's even more complicated: they have two letter Is, one with a dot in both lower and uppercase (İ/i) and one dotless (I/ı) in both cases. So any automatic case change needs to take this into account or the letter will get switched. This also make using fonts with fi ligatures problematic. http://en.wikipedia.org/wiki/Dotless_I http://en.wikipedia.org/wiki/Dotless_I
