in reply to HTML::Entities encode_entities for perlmonks [ ]

Update: Do two runs of encode entities to encode normal characters first time and your special characters the second time. This may be a little slower than doing one pass but means you don't have to specify exactly what else you need to encode.

my $string = '[I haz square brackets]';
my $unsafe_chars = '[]';
# first pass encodes default set
my $pass1= encode_entities( $string );
# second pass encodes speshul chars
my $encoded = encode_entities( $pass1, $unsafe_chars );

    Nice try 

    #!/usr/bin/perl --
use strict;
use warnings;
use HTML::Entities ;
my $string = '[< smarto  >]';
my $unsafe_chars = '[]';
my $encoded = encode_entities( $string, $unsafe_chars );
print "$string\n$encoded\n";
__END__

    The question is what to add encode_entities to also encode  [ ] -- I want what the default encode_entities does plus  [ ]

      Next time be a bit more precise with your question! :-)

      You could simply run a first pass of encode_entities with no params so it would encode the default values, and the second pass with any special characters you also need encoding. I've amended my original answer accordingly.

      Why not just encode the other characters manually? 
      use HTML::Entities ;

my $string = '[< smarto  >]';

my $unsafe_chars = '[]';
my $encoded = encode_entities($string)
                =~ s{([\Q$unsafe_chars\E])}{sprintf"&#%d;",ord$1}egr;

print "$string\n$encoded\n";
