title: Stray "\303" and stray "\215" in program -- why?
body: <p>Instead of stray "\302" in program for which I found <a href="https://stackoverflow.com/questions/5167656/error-stray-302-in-program">here</a>, I got the error message:</p>
  
  <pre><code>algo.c:118: error: stray ‘\303’ in program
  algo.c:118: error: stray ‘\215’ in program
  </code></pre>
  
  <p>I could not seem to figure it out , what is this?</p>

  <p>For future reference, stray '\XXX' means an incomprehensible character to the compiler. The way to fix is to find the '\XXX' character (which now I find out is not always this unicode, it can't be a wrong definition, such as '##' in '##define'), then delete or correct it. Good luck!</p>
