There is John Walker's codegroup utility: http://fourmilab.ch/codegroup/ http://fourmilab.ch/codegroup/ Only codegroup conforms to the telegraphic convention of all upper case letters, and passes the “telephone test” of being readable without any modifiers such as “capital” and “lower-case”. Avoiding punctuation marks and lower case letters makes the output of codegroup much easier to transmit over a voice or traditional telegraphic link.
