Subject: bug#36718: uniq treats distinct Korean characters equal

Thanks @Paul Eggert, it seems like this isn't a bug at all.

My locale (de_DE.utf8) appears to lack definitions for the mentioned
Korean characters. After setting my system language to Korean
(ko_KR.utf8) uniq produces the expected output.
For my purpose, I'll set my environment to LC_COLLATE=C, which forces
byte-wise comparison and should work for all languages.

Admittedly, I could've searched it:
