I am about to test a software's handling of diacritics.
a sign, such as an accent or cedilla, which when written above or below a letter indicates a difference in pronunciation from the same letter when unmarked or differently marked.
Wikipedia's diacritics article shows many examples. But I could not find a compilation of such characters for designated use in testing software anywhere online.
Do you know of any test data repositories? Regarding strings in general or diacritics in particular.
