in thread Mixed Unicode and ANSI string comparisons?

No, as far as perl is concerned, you start with 4 Unicode strings and get 8 Unicode strings... in different storage formats. utf8 flag says pretty much nothing about "Unicodeness".
And now I remembered that LATIN_SMALL_LETTER_C_WITH_CEDILLA is codepoint 231 and you didn't use feature 'unicode_strings' (or, more commonly, use 5.012)... So yeah, you had 3 Unicode strings and 1 non-Unicode, "c" being Unicode (utf8 off), CEDILLA non-Unicode (utf8 on...) Interesting, isn't it? :)

    Adding unicode_strings doesn't change the output in any way.

      It doesn't change sort, but it would change some other operations though.
