Exactly. There is absolutely no point in changing your code to  
unicodestring in reaction to these changes (nor in reaction to future  
changes an sich, if we can help it). There's not even any point to  
changing your code at all in many cases. And all functionality that  
has been added is indeed also available when using single byte  
strings, as explained on the FPC_Unicode_support page.

The main reason so few RTL-level features are supported yet is exactly  
because it takes a lot of planning and energy to keep functionality as  
backward compatible as possible. If we had just abandoned backward  
compatibility and made everything UTF-16 only, we would probably have  
finished a long time ago.
