-        As from ERTS 9.0 (OTP 20), atoms may contain any Unicode
-        characters. Atoms sent over node distribution are always encoded
-        in UTF-8 using either

-        for atoms that only contain Latin-1 characters (Unicode code points 0-255).
-      </p>
-      <p>The maximum number of allowed characters in an atom is 255. In the
-        UTF-8 case, each character can need 4 bytes to be encoded.</p>
