Fixed bug 5524 - Pass NSString to NSLog()

Hiroyuki Iwatsuki

If you pass the C string directly to NSLog(), it will be garbled with Japanese and probably other language strings, or no log will be output at all.

NSLog("Hello, World!"); // => "Hello, World!"
NSLog("こんにちは、世界！"); // => No output...

Therefore, you need to convert the string to an NSString before passing it to NSLog().

NSString *str = [NSString stringWithUTF8String:"こんにちは、世界！"];
NSLog(@"%@", str); // => "こんにちは、世界！"

Thank you.
