No, that fails to address nearly all the use cases of escaping. Escaping is the difference between printf(&quot;\n&quot;) and printf(&quot;n&quot;), or between printf(&quot;d&quot;) and printf(&quot;%d&quot;), or between (dog|cat)* (any number of repetitions of &quot;dog&quot; and &quot;cat&quot;) and \(dog|cat\)* (a left paren, exactly one instance of &quot;dog&quot; or &quot;cat&quot;, and any number of right parens). Those aren&#x27;t differences of length. The only scenario marked length helps with is situations like &quot;I need to use \&quot;scare quotes\&quot;&quot;.
