Ok, so the terminal emulator is responsible for caring about this.
KGI passes plain UNICODE keycodes (with some vendor specific extensions)
to the terminal emulators, which then do the function key -> string
mapping. As terminal emulators (in KGI) are instantiated per-virtual
this issue (which actually is emulator specific) can be addressed
inside the terminal emulators. 

However, currently KGI assumes function keys are focus-local, but
this can be made device (virtual terminal) local with a few
straightforward changes in two functions in the KII implementation.

So far KGI contains a dumb console terminal emulator (no ESC sequences
are parsed) and a fairly clean and complete xterm/vt100 emulation with
optional linux-console extensions. Others can easily be added.
