Will compilations with `--release N-1` wind back the set of allowable

I don't think `javac --release` takes the Unicode version into account.
That is a bug.
Yes.
I agree with your comment that the CSR could be be expanded to at least make it
clear that if support for a currency symbol is added in some future update of
JDK N then source code using it in identifiers will compile with the JDK update
that supports the symbol, not by the GA or previous updates of JDK N.
The question is whether, or not, it is reasonable to allow ( part of )
the set of Java identifiers, in the language, to be an implementation
detail? If so, then certain code compiled and run on BuzzCorps Java
implementation may not compile or run on WollyInc's Java implementation.
( Both are compliant Java SE implementations )
I accept that the set of implementation specific currency characters
may noy be all that large, but this does seem like a significant
change, and I want to ensure that the implications are fully understood.
Agree. It's good to have more insights here. I will need to wait for
someone more appropriate to answer to this question.
