  Returns:

  true if the first N bytes are zero

• sanitize

  public static String sanitize(String s)

  Returns a "sanitized" version of the string given as arguments, where sanitized means non-printable characters have been replaced with a question mark and the outcome is not longer than 255 chars.

  This method is used to clean up file names when they are used in exception messages as they may end up in log files or as console output and may have been read from a corrupted input.

  Parameters:

  s - the string to sanitize

  Returns:

  a sanitized version of the argument
