OC中怎样将UTF8编码转换成中文

Question

如题：有一个Person类，里面重写了description方法，实现返回姓名，年龄等信息。这样我可以直接通过NSLog(@"%@",per); 来输出对象信息。但是如果我把对象存入数组中，然后输出数组：NSLog(@"%@", array);这样输出的结果都是UTF8编码。如果对象per内部的信息是因为和数字的话结果不受影响，如果是中文的话输出的就是UTF8。这是为什么呢？如果才能让输出正常？

#import

@interface Person : NSObject

@property(nonatomic, retain) NSString *name;
@property(nonatomic, retain) NSString *sex;
@property(nonatomic, assign) int age;

• (id)initWithName:(NSString*)name;

@end

///////////////////////////////////
#import "Person.h"

@implementation Person

• (id)initWithName:(NSString *)name
  {
  if( (self = [super init]) != nil )
  {
  self.name = name;
  }
  return self;
  }

• (NSString *)description
  {
  return [NSString stringWithFormat:@"姓名：%@\t性别：%@\n年龄：%d", _name, _sex, _age];
  }

/////////////////////////////////

#import
#import "Person.h"

int main(int argc, const char * argv[])
{

Person *per1 = [[Person alloc] initWithName:@"张三"];
Person *per2 = [[Person alloc] initWithName:@"张三"];
Person *per3 = [[Person alloc] initWithName:@"张三"];

per1.sex = @"男";
per1.age = 230;

NSLog(@"%@", per2);     //输出正常
NSMutableArray *array = [NSMutableArray arrayWithObjects:per1,per2, per3, nil];
NSLog(@"%@", array);        //输出不正常

return 0;

}

求大神解救！！！
