Bug#139861: This bug is still present.

[Margarita Manterola]

I've just verified, and with version  5.2.1-2 of coreutils, I can still
reproduce the bug:

using LANG=es_AR.UTF8

$ echo ��� | tr ��� ���
���

$ echo ��� | tr [:lower:] [:upper:]
���

$ echo aei��� | tr [:lower:] [:upper:]
AEI���

$ echo ��� | grep [[:lower:]]
���

Please try and fix it.
