Hello, World! in Unicode?
-
Dear list,
The XCode supplied template "Foundation Tool" does not do Unicode as I
hoped. It prints the danish characters wrong.
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog(@"Hello, Jxrgen Xstergerd!"); //Name with 3 danish letters
[pool release];
return 0;
}
The C and C++ "Hello, World!" templates work.
Thanks,
Henrik

The ObjC static strings with the @"" notation doesn't support non-ASCII
text. This is documented in the ObjC PDF. Suggestions for how to work
around this can be found in the list archives.

The current compiler does not support non-ASCII characters in source
files so you can't make Unicode string constants. The proscribed
method for dealing with this is to use the application localisation
facilities. So you might for instance use:
NSLog(@"Hello, %@!", [[NSBundle mainBundle] localizedStringForKey:
@"John Bull" value: nil table: nil]);
and then put a mapping in the application bundle's Danish
Localizable.strings between "John Bull" and "Jxrgen Xstergerd".

While it is best to use the localization system whenever possible,
instead of hard-coding strings, it *is* possible to use non-ASCII
characters in source, as long as you can ensure the encoding of the
source file. For instance, if you know that the source code is in
UTF-8, you can do the following:
/*The characters may have been munged by the mailing list, but you get
the idea*/
NSString *foo = [NSString stringWithUTF8String: "String containing
Unicode characters: $B;d$O%/%i!<%/$G$9!#(B"];
This works especially well with UTF-8, as there is no way that any
sequence of bytes can be mistakenly taken as an escape sequence (i.e.
the only way that the byte representing the ASCII backslash can occur
is if you've actually typed the backslash), you might not be so lucky
with other multi-byte encodings.
