Re^2: 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; [[ é =~ [a-z] ]] \|\| echo no) $ (LC_ALL=C; [[ é =~ [a-z] ]] \|\| echo no) no $ perl -Mutf8 -wE 'say "é" =~ /[[:lower:]]/' 1 $ perl -Mutf8 -wE 'say "é" =~ /[a-z]/' $` [download] Update: Switched from <c> to <pre> and back. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

[a-z]

$ (LC_ALL=en_US.UTF-8; [[ é =~ [a-z] ]] || echo no)
$ (LC_ALL=C; [[ é =~ [a-z] ]] || echo no)
no
$ perl -Mutf8 -wE 'say "é" =~ /[[:lower:]]/'
1
$ perl -Mutf8 -wE 'say "é" =~ /[a-z]/'

$

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

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