Comment 12 for bug 75705

latimerio, thanks for looking at this. In comment #2 I verified that it doesn't have anything to do with "sort" per se, but it's really a libc (specifically strcoll) issue. My best test case are the strings

aa
aá
áa
áá

which should sort as they appear above (since a < á), but still sort like this:

aa
áa
aá
áá
