I'm not so sure. It has often been said, here and elsewhere, that non-
ASCII characters cannot be used in source files, and that you'd need to
load such a string from a .strings or .plist file. I'm not sure why this
is the case, its so 1990s. :)
It is also often said that Obj-C is a strict superset of C, but C (C99
anyway) does allow non-ASCII variable names, comments, strings, etc. For
example,
int \u30AD\u30B3\u30DE\u30A6 = 420;
is valid C, so should be valid Obj-C. It compiles in CodeWarrior 9.4
though I just tried and gcc 3.3 does not accept it.
So is it invalid Obj-C to use non-ASCII strings in source, or is it
disallowed just because gcc is not C-compliant, or is Obj-C not C99-
based, or what? I do wish there was an ISO Obj-C standard. :)
