Will there be problems for EBCDIC systems? AFAIK, C++ dropped support
for EBCDIC the moment there was no IBM representative in WG14. But C
still supports it.

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


P.S.: A related topic, but far less ambitious: Would it make sense to
add @ and $ to the basic source character set
(http://www.colecovision.eu/stuff/proposal-basic-@.html)? AFAIK, this
should work for implementations that use ASCII (or an extension, such as
UTF-8) as well as those that use an EBCDIC code page that can be used
for C programming today.

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!)
