Do not to use Unicode characters
Looking over the 1.1 million possible Unicode characters makes it impossible to actually implement this into an application. Yes I can use someone else's application but I cannot write my own in a realistic amount of time.
I don't believe that Unicode is going to advance technology. It will hinder development to a point of disaster. My wife asks me why rectangles appear on her text messages. It's back to the application dependent character sets. Variations in technology is not going to work. It of course helps monopolies, "rely on us, give us 20 years and we will fix it". It restricts free trade in information technology, which is to their benefit.
To build a character-set that is application independent is the objective. The PDF tried to implement this and it almost worked. They had to fall back on application specific code for the larger font sets (Chinese, Korean,...)
We tries font encoding. This actually works, a fairly simple logic, but without support it becomes impossible to implement, due to the lack of tools and structures that should be supplied by the "people" that create the "standards". The huge failure is just the names that were used "ISO8859-2" , so I suggest simply give known names to the encodings ("Czech",...).
Fonts, are of course the whole reason that technology is were it is at. Restrict access to fonts. and you restrict information technology. This of course goes along with, restrict access to the screen and you control the world.
Jane will provide access to the screen and to fonts at the compiler level. This remove the need to use any specific character coding scheme. Once the restriction are removed, information technology can grow.
