The source character set and/or execution character set may contain locale-specific, extended characters outside the basic character set.https://port70.net/~nsz/c/c11/n1570.html#5.2.1
I still have a small doubt. C23 added '@' to the source character set, but seems to be a second-class citizen:
The execution character set may also contain multibyte characters, whichneed not have the same encoding as for the source character set. For both character sets, the following
shall hold:— The basic character set, @, $, and ` shall be present and each character shall be encoded as a
single byte.What's the difference, and why isn't it part of the basic character set? Maybe because not all keyboards have those three characters?
