Morse was always a personal favorite and I have been playing around with it through my own ham experience some 10 years ago. It's interesting to think about improving the old model for a full-featured keyboard. SMS has evolved in a similar fashion once people realized how costly long words are (speed and tariffs) - but these shortcuts are also demonstrating the fact that it is not as effective as a full keyboard. Language and "intelligent" systems are something I would rather avoid. Dictionaries and countless other issues must be addressed, and as a person who uses two main character sets I am very sensitive to the subject. The links you provided are very interesting. I didn't consider other languages and it opened my eyes a bit. I will bear this in mind it through the rest of our journey.
