Yes, that's true.  You can see the sources for CFString in the Darwin
source tree.  Furthermore, string constants (even @"" and CFSTR("")
ones) are encoded in ASCII by the compiler, which makes 8-bit strings
quite common in practice.


FYI: As of Leopard, this is no longer necessarily true (i.e. the
string constants being ASCII). Full UTF-8 strings are now supported
within @"" and CFSTR("") strings, so there are cases where even these
strings are encoded as UTF-16 by the compiler.

As of Leopard or as of Xcode 3.x? And, if I read the paragraph above correctly, the compiler will expand @"UTF-8 string" in the source code to UTF16 in the string constant in the TEXT section?
