[12] RFR: 8215303: Allowing additional currency code points from later Unicode updates

[naoto.sato at oracle.com]

Hi Chris,

Yes, it will affect the behavior of those methods. This has been 
discussed within the JLS folks, and their understanding was that the 
risk is minimal and OK to proceed. I was not involved in the discussion, 
but here are the reasons I can think of.

- The Currency Symbols range is very limited (U+20A0-U+20CF)
- The change is to allow the code point, not the way around, so existing 
identifiers are guaranteed to work.
- Apart from this CSR, this kind of behavior change is common when a 
Unicode upgrade is done.
