    data is like:
    "my data^A77789^B^Bmore data"; i tried to match it using "/(data^A)(\d+)^B/", i would expect:
    $1 = data^A
    $2 = 77789
    however, it didn't work. (note: ^A is one character)

      By ^A do you mean Control-A (i.e. chr(1)?

      If so, use this: 

      if ($input =~ m/(data\x1)(\d+)\x2/) {
  print "1 = $1, length = ", length($1), "\n";
  print "2 = $2\n";
}
