Yes, it is. But I have just fixed it and in the next few hours I will
release a new version.
Thanks for replying,

Hola Julio,
Could this be why I get chinese characters when I use your
FetchYourLyrics program on my MBP?

After reading and thinking (thanks Chris Suter) I guess I found a
solution for this problem. Instead of using an NSString to get the
value from iTunes, I used a CFString:
CFStringRef myCFString;
#if __BIG_ENDIAN__
myCFString = CFStringCreateWithBytes
(kCFAllocatorDefault,myValue,mySize,kCFStringEncodingUnicode,true);
#elif __LITTLE_ENDIAN__
myCFString = CFStringCreateWithBytes
(kCFAllocatorDefault,myValue,mySize,kCFStringEncodingUnicode,false);
#endif
myString = (NSString*)myCFString;
Note that the only difference between the calls to
CFStringCreateWithBytes is the last parameter, which is a boolean
that forces the function to swap bytes when false. This parameter
does not exist in [NSString stringWithBytes:]. As Intel based macs
are 'Little Endians' the problem now is solved. I do not know if
this is the most elegant way to do this but it works.

Hi,
I am facing a strange problem with an app that I am developing.
It retrieves information from iTunes (song name, artist, etc.)
and all my tests were successful (I am using a ppc based mac).
But some users have reported strange chinese characters showing
up even when iTunes displays latin characters. Reviewing the code
I am using to retrieve the strings from iTunes it works this way:
an NSString is created using initWithBytes method, an Unichar
variable as the parameter and NSUnicodeStringEncoding as the
encoding.
The users that are complaining use intel-based macs so I think
this is a big-endian/little-endian problem. How can I handle this
situation? Checking for __BIG_ENDIAN__ and __LITTLE_ENDIAN__ ? I
searched the list archives but did not find any useful
informartion so any help would be appreciated.
