Um, I don't think that will work. @"" strings only work with ASCII because there is no encoding specified. They might coincidentally work with MacRoman at present, but this is not guaranteed behavior, and the docs specifically warn against relying on this.


The \u notation is specified in C99, and it's certainly accepted by Apple's gcc when using the -std=c99 option. However, I was surprised to see that while the compiler accepted the code, the result wasn't what I had expected.

My guess is that gcc erroneously does in fact let the string pass through some locale encoding, even though it shouldn't. The \u notation is supposed to allow you to enter Unicode values in the code without having to worry about the encoding of the local system that runs the compile.

GCC isn't mangling the string. @"" is designed to take ASCII encoding, not UTF8 or MacRoman or anything else. What you'll get for any character above 127 is just undefined. Why Apple/NeXT chose to make @"" work this way, I don't know, but that's the situation. _______________________________________________
