This is exactly what should be done with the Turkish Lira.
No, because the existing character could be or could have been used for other
liras.
Correct. And as for the other characters mentioned, the case is not so
different - they could be or could have been used for some other
purpose. Neither Unicode nor 10646 controls in any way how characters
are used. Instead, there's the express guarantee: characters will not
change. So if you found that some existing character serves a particular
purpose, be it in designating a currency or in some other notation, you
are guaranteed that the character is stable - your documents will not be
corrupted just because some experts or other at some future committee
meeting decide that they know what the character "should have been used
for".
