如何从NSString中删除/替换/显示Unicode字符

Question

I'm parsing http://maps.google.com/maps/geo?q=48.209946,11.539421&output=csv . The response is 200,8,"Lerchenstraße 66, 80995 Munich, Germany". I'm only showing the CityName ie, "Lerchenstraße 66". But the problem is that the CityName string has Unicode characters, and it is showing like "Lerchenstra\\U00dfe66" in the view. The output should be like "Lerchenstrasse" or "Lerchenstraße".

-(void) httpDataDidFinishLoadingWithData:(NSData *)theData {
  m_activityLoaded=NO;
  temp=[[NSString alloc] initWithData:[dataLoader httpData] encoding:NSUTF8StringEncoding];
  NSArray *listItems = [temp componentsSeparatedByString:@","];
  NSArray *tempCountryArray = [[listItems objectAtIndex:[listItems count]-3] componentsSeparatedByString:@"\""];
  NSString *string = [NSString stringWithFormat:@"%@", tempCountryArray];
  NSString *strTe=[[[[string
    stringByReplacingOccurrencesOfString:@"(" withString:@""]
    stringByReplacingOccurrencesOfString:@")" withString:@""]
    stringByReplacingOccurrencesOfString:@" " withString:@""]
    stringByReplacingOccurrencesOfString:@"\"" withString:@"" ];
  self.cityNameString = strTe;
  NSLog(@"CITY NAME IS : %@", strTe);
}

Please help me. Thanks in advance.

I got the answer. Thanks for the support and suggestions. The code is:

NSString* esc1 = [strTe stringByReplacingOccurrencesOfString:@"\\u" withString:@"\\U"];
NSString* esc2 = [esc1 stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];
NSString* quoted = [[@"\"" stringByAppendingString:esc2] stringByAppendingString:@"\""];
NSData* data = [quoted dataUsingEncoding:NSUTF8StringEncoding];
NSString* unesc = [NSPropertyListSerialization propertyListFromData:data
  mutabilityOption:NSPropertyListImmutable format:NULL
  errorDescription:NULL];
assert([unesc isKindOfClass:[NSString class]]);
NSLog(@"Output = %@", unesc);

And the output is "Lerchenstraße66".
