paragraph justified text does not work with embedded fonts because word spacing only applies to x20 ascii char

according to PDF32000-1:2008 specifications for PDF1.7 point 9.3.3 at pages 244-245 and point 9.4.3 at pages 250-251 I suggest to change or overclass function text_fill_justified as follows for a better management of justified text.

*PDF::API2::Content::text_fill_justified =
sub {
    my ($self, $text, $width, %opts) = @_;
    my ($line, $ret) = $self->_text_fill_line($text, $width);
    my $ws = $self->wordspace();
    my $w = $self->advancewidth($line);
    my $space_count = (split /\s/, $line) - 1;

    # Normal Line
    if ($ret) {
        #$self->wordspace(($width - $w) / $space_count) if $space_count;
        #$width = $self->text($line, %opts, align => 'left');
        #$self->wordspace($ws);
        my $s = $self->advancewidth(' ') + (($width - $w) / $space_count) if $space_count;
        my @words = split /\s/, $line;
        $width =0;
        foreach my $word (@words){
            $width += $self->text($word, %opts, align => 'left');
            $opts{indent} = $s if $space_count;
        }
        return $width, $ret;
    }

    # Last Line
    if ($opts{'align-last'}) {
        unless ($opts{'align-last'} =~ /^(left|center|right|justified)$/) {
            croak 'Invalid align-last (must be left, center, right, or justified)';
        }
    }
    my $align_last = $opts{'align-last'} // 'left';
    if ($align_last eq 'left') {
        $width = $self->text($line, %opts, align => 'left');
    }
    elsif ($align_last eq 'center') {
        $width = $self->text($line, %opts, align => 'center');
    }
    elsif ($align_last eq 'right') {
        $width = $self->text($line, %opts, align => 'right');
    }
    else { 
        #$self->wordspace(($width - $w) / $space_count) if $space_count;
        #$width = $self->text($line, %opts, align => 'left');
        #$self->wordspace($ws);
        my $s = $self->advancewidth(' ') + (($width - $w) / $space_count) if $space_count;
        my @words = split /\s/, $line;
        $width =0;
        foreach my $word (@words){
            $width += $self->text($word, %opts, align => 'left');
            $opts{indent} = $s if $space_count;
        }
    }
    return $width, $ret;
};
