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.

A list of data for testing diacritics can be found at http://www.madore.org/~david/misc/unitest/#accents

  • Just what I was looking for, and many more useful test data, like Arabic, Greek and Chinese texts. Commented May 13, 2017 at 15:57

The Big List of Naughty Strings is another good one - it's not just diacritics, but a whole lot of different unicode strings and a bunch of other strings that are known to cause problems in different applications.
