in thread Efficient way to verify scalar contents

Please correct me, but do these character classes not depend on localisation?

[[:lower:]] [[:upper:]]

I think passwords should rather be defined in terms of ASCII

    I'm not sure. I remember [a-z] depending on locale, but it was probably in bash rather than Perl...
    $ (LC_ALL=en_US.UTF-8; [[ =~ [a-z] ]] || echo no) $ (LC_ALL=C; [[ =~ [a-z] ]] || echo no) no $ perl -Mutf8 -wE 'say "" =~ /[[:lower:]]/' 1 $ perl -Mutf8 -wE 'say "" =~ /[a-z]/' $

    Update: Switched from <c> to <pre> and back.

    map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
