Are there standard perl functions for escaping and de-escaping a string? For example, if the five characters [\',"?] are considered "special" in some context and need escaping, and the single character [\] is the escape character, then escaping the string
yo, what's a "henway"?
would result in
yo\, what\'s a \"henway\"\?
and similarly, de-escaping the second string would result in the first.
Given perl's rich set of regex functions, I know this is simple to write, but I've also learned that nearly everything worth writing has been already written. Has it?
