Morse code for non-Latin alphabets

This is a summary of the use of Morse code to represent alphabets other than Latin.

Greek

The Greek Morse code alphabet is very similar to the Latin alphabet. It uses one extra letter for Greek letter Χ and does not use the codes for Latin letters "J", "U" and "V".

The tonos is not transmitted in Morse code; the receiver can simply infer which vowels require one. The Greek diphthongs presented in the bottom three rows of the table are specified in old Greek Morse-code tables but they are never used in actual communication, the two vowels being sent separately.

Cyrillic

Cyrillic letters are represented using the representation of similar-sounding Latin letters (e.g. Б≡B, В≡W (German pronunciation), Г≡G, Д≡D, etc.). Cyrillic letters with no such Latin correspondence are assigned to Latin letters with no Cyrillic correspondence (e.g. Щ≡Q). The same correspondence was later used to create Russian national character sets KOI-7 and KOI-8.

This order and representation reflects the Russian national standard. The Bulgarian standard is the same except for the two letters given in parentheses; the Bulgarian language does not use Ы, while Ъ, missing in the Russian standard, is frequent. The letter Ё does not have a Morse equivalent, with Е used instead.

Hebrew

Hebrew letters are mostly represented using the Morse representation of a similar-sounding Latin letter (e.g. "Bet" ב≡B); however the representation for several letters are from a Latin letter with a similar shape (e.g. "Tet" ט ≡U, while "Tav" ת≡T).

The following telegraph code table is adapted from one given by Ashok Kelkar,^[1] where the Latin letters are encoded as per the International Morse code standard. Some variations on this code exist,^[2] and there have been some attempts to introduce other telegraph codes to add efficiency and make it suitable for more Indian languages.^[1][3]
