Back in the 50s Alfred Bester wrote a very fine science fiction novel titled The Demolished Man, about a community with telepathic members (but only some). He wrote with an extended-yet-compressed alphabet: "1/4maine" for Quartermaine, "@kins" for Atkins. That was only presented in the serialized version (Galaxy Science Fiction, AIR) and was expanded later in the novelized publication. Too subtle for the general public, was always my interpretation.
