In Morse code, a dot is added to C and J to derive Ĉ and Ĵ, a dash–dot is added to G and S to derive Ĝ and Ŝ, a dash is added to U to derive Ǔ, and the four dots of H are changed to four dashes for Ĥ. However, users often substitute these novel letters with digraphs ch, gh, jh, sh etc.Lenio Marobin, PY3DF (2008) 'Morsa kodo kaj Esperanto – rekolekto de artikoloj iam aperintaj', ILERA Bulteno n-o 70, p-o 04.
