My Exchange server always finds my friend when I search for "Kivanc" even though the "i" and the "c" are Turkish letters without a dot and with a squiggle respectively. However, I cannot get it to find my friend Nikolay when I type the whole thing, as it doesn't match the final Cyrillic letter with my "y". I would say, in general, string matching leaves a lot to be desired, especially when I don't know how to actually type most of the letters of my colleagues's and friends's names. (It's easier on Mac than Windows 10 though - I can't figure out a dang thing for Windows 10 that is not English.)
