  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,
  "1".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
