Morse code encoded the same way (A, O, E, I, T, M, N, R, K, etc.). Bulgarian alphabet contains 30 characters, which exactly match all possible combinations of 1, 2, 3, and 4 dots and dashes. Russian requires 1 extra character, "Ы" which is encoded with 5 elements. During early World War I (1914–1916), Germany briefly experimented with 'dotty' and 'dashy' Morse, in essence adding a dot or a dash at the end of each Morse symbol. Each one was quickly broken by Allied SIGINT, and standard Morse was restored by Spring 1916. Only a small percentage of Western Front (North Atlantic
Esperanto orthography diacritic letters. An Esperanto braille magazine, "Aŭroro," has been published since 1920. 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. There is a proposed manual alphabet as part of the "Signuno" project. Signuno itself, as signed Esperanto rather than a language in its own right, is a manual logographic Esperanto orthography. The Signuno alphabet derives from international
