Yes, the issue is the missing uppercase ? it seems (though when children
learn the alphabet that character is always sorted after all others, not
after the s like in the dictionaries, no consistency there ;-) )...
And I now found that a few lines above it does mention some of the
problems with ranges.
Though it seems to me that this behaviour means that unless you set the
locale before, range expressions are just useless because there is no
way to use them reliably.
Oh well, is there anyone who knows a problem with the long way to write
it? Or can we just use that?
