Indeed, just like any other {$mode xxx} and {$modeswitch xxx}  
directive. I don't think we have any directive or switch that can  
cross compilation unit boundaries.

Technically, it would also be very hard to make e.g. {$modeswitch  
unicodestring} affect other units that you use. After all, the source  
code for those other units may not be available, and they would have  
to be recompiled if the meaning of "string" changed in their source  
code.
