    text.encode('string_escape') does not seem to satisfy our needs as it
    encodes unprintable characters using two-digit hex escapes whereas our
    C++ unescaping function allows hex escapes to be any length.  So,
    "\0011".encode('string_escape') ends up being "\\x011", which will be
    decoded in C++ as a single-character string with char code 0x11.
  
    Args:
      text: A byte string to be escaped
      as_utf8: Specifies if result should be returned in UTF-8 encoding
    Returns:
      Escaped string
