I see no error. You do not include Z into [a-z] expression above, so why
you expect it is unknown.

No, it is not case-equal sorting. As I already mention, it is
dictionaries sorting, letters considered first, their case - next (and
maybe many other factors for non-ASCII - next).

Admin should either run C or US-ASCII locale or do not use a-z ranges
without knowing sorting on his locale.

I see no errors in your sh examples.

In general it was decided (not by me) to use CLDR collation since it is
able to stable sort all Unicode chars.
