Unicode identifiers happen in C++ after phase 1 and so neither the source
encoding nor the execution encoding are impacted.

It's actually more ambitious I am afraid. This question is asked
frequently in WG21 and 2 arguments against it are
@ is used by objective-c(++) and $ is 1/valid in identifiers in some gcc
implementation extension 2/ used by code generators.
(On a personal note, I think $ would be useful for e.g reflection syntaxes
but that is an uphill battle!)
