Hi,
So currently the words are trimmed of non alphabets before the check:

while ($rawline =~ /\b($word_pattern) (?=($word_pattern))/g) {
my $first = $1;
my $second = $2;

where, the word_pattern is:
my $word_pattern = '\b[A-Z]?[a-z]{2,}\b';

So do you perhaps recommend modifying this word pattern to
include the punctuation as well rather than trimming them off?

Thanks,
Dwaipayan.
