title: How to use the chr function inside a regular expression in Perl?
body: <p>I have a Perl script which has a string which may or may not contain character 146 in the ASCII character codes. I'm interested in using the chr() function inside a regular expression to find out if that string really does contain that character. If the character is there, I would like to substitute it with a "'" character.</p>
  
  <p>Is this possible? If not what's another way to do this?</p>
  
  <p>This one has my stumped. Thanks!</p>
