title: Comment Illegal Unicode Sequences
body: <p>I was once working on a Java application dealing with unicode processing - and as usual to begin with, I write some code and test it, then comment out the working code and add some new lines., and this process goes on till I find the solution </p>
  
  <p>The exact issue I had was commenting out illegal Unicode strings. Some unicode wasn't working and I wanted to just comment it out.. to my utter surprise, it wouldn't work.</p>
  
  <p>Example Code:</p>
  
  <pre><code>class UnicodeTester{
  //char someCharacter = "\ux13d";
  }
  
  javac UnicodeTester.java
  
  UnicodeTester.java:2: illegal unicode escape
  //char someCharacter = "\ux13d";
                                ^
  1 error
  </code></pre>
  
  <p>Is there a way where I can comment out illegal unicode sequences?? I read the Java Language Specification 2.2 &amp; 2.3, The Lexical Grammar is enforced before  the Syntactic Grammar. PERIOD. But what is the most effective workaround other than removing them from the source code??</p>
