open (A1, "<2 normaal.txt") or die "can't open";

my @MainArray;

while (<A1>)
{
    my $in = $_;
    chomp $in;
    push (@array1, split(//, $in));
}

Another way to do it: 

open my $A1, '<', '2 normaal.txt' or die "can't open '2 normaal.txt' b
+ecause: $!";

my @MainArray;

while ( my $in = <$A1> ) {
    push @MainArray, [ $in =~ /[[:alpha:]]/g ];
}
