Change Tracking

[Michael Gerz]

All,

it seems that the unicode migration will not be completed soon. This 
makes me wonder whether I am allowed to merge my CT branch with the 
trunk. I am fully aware that my work in not completely finished (I guess 
that about 95% of the code is ready). On the other hand, I added FIXME 
whereever I was uncertain about the current solution. Maintaining the CT 
branch forever will inevitably result in broken code, in particular if 
others shift code from one file to another.
