Hi Kevin,

Thanks for the response. I get the same thing as postgres if I sort from
the command line too. But I don't understand why.
Because that is how en_US.UTF-8 sorts. You are probably looking for the
'C' sort order. For more explanations see:

http://rhaas.blogspot.com/2012/03/perils-of-collation-aware-comparisons.html

http://superuser.com/questions/227925/in-utf-8-collation-why-11-is-less-then-1

I would expect '-F' to sort immediately after '-' and '--' not after 'F' as
well as ' Feneric' (spaceFeneric) and ' Generic' (spaceGeneric) to sort
immediately after ' ' (space).

It is like the space character and the - in -Letter is ignored.
See the second link above for why that is.



Thanks Adrian and Kevin,

for the explanations and links. They were very elucidating. At least now I understand what is happening.

Thanks again.
