in reply to How to generate random sequence of UTF-8 characters

it would be trivially simple

But very long-winded! Perhaps using Range Operators and map would save some typing?

$ perl -Mstrict -Mwarnings -E ' > my @chars = q{0} .. q{9}; > push @chars, map { $_ => uc } q{a} .. q{z}; > say for @chars;' 0 1 2 3 4 5 6 7 8 9 a A b B c C ... y Y z Z $

This does not address your problem but I hope it is of interest.

    Here's another way:

    my @chars = ( 0..9,'a'..'z','A'..'Z' ); print @chars; __DATA__ 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

    update: And one more:

    my $string = join '',0..9,'a'..'z'; $string =~ s/([a-z])/$1\u$1/g; print $string; __DATA__ 0123456789aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ

      Thanks lotus and JohnGG. Both solutions are quite interesting.
