Difficulty parsing response containing characters like '\u00' - iphone

Question

I am using NSXML Parser to do parsing in my iPhone app. Now everything works fine except when data comes in French language.
For example, data from server comes as Ch\u00e9rie FM.
Now under the string argument of foundCharacters method, I only get string as 'Ch' rest of the characters don't come up. So finally my string is truncated only to 'Ch' intead of the whole Cherie fm
What could be done?
Code:
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict
{
if (appDelegate.objPlayer.fromFlickrorRecommend == TRUE)
{
if([elementName isEqualToString:#"outline"] && [[attributeDict valueForKey:#"text"] isEqualToString:#"You may also like"])
{
flagCheck = 1;
}
else if ([elementName isEqualToString:#"outline"] && [[attributeDict valueForKey:#"text"] isEqualToString:#"Genres"])
{
flagCheck = 0;
}
if (flagCheck == 1 && [elementName isEqualToString:#"outline"])
{
if([[attributeDict valueForKey:#"type"] isEqualToString:#"audio"])
{
[appDelegate.objPlayer.recommendDataArray addObject:attributeDict];
}
}
}
else
{
if ([elementName isEqualToString:#"location"])
{
flagCheck = 2;
}
else if ([elementName isEqualToString:#"url"])
{
flagCheck = 3;
}
else if ([elementName isEqualToString:#"name"])
{
flagCheck = 4;
}
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if (flagCheck == 2)
{
flagCheck = -1;
appDelegate.objPlayer.flickrCity = string;
}
else if(flagCheck == 3)
{
flagCheck = -1;
appDelegate.objPlayer.stationURL = string;
}
else if(flagCheck == 4)
{
flagCheck = -1;
appDelegate.playStationName = string;
}
//else if(flagCheck == 0) // change
// {
// appDelegate.playStationName = string;
// }
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
//if (flagCheck == 1 && [elementName isEqualToString:#"outline"])
// {
// [appDelegate.objPlayer.recommendDataArray addObject:dataDictionary];
// dataDictionary = nil;
// [dataDictionary release];
// }
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string may be called multiple times so you need to accumulate the characters found into an NSMutableString. There is an example of how to implement this in the Event-Driven XML Programming Guide.
The parser object may send the delegate several
parser:foundCharacters: messages to report the characters of an
element. Because string may be only part of the total character
content for the current element, you should append it to the current
accumulation of characters until the element changes.
Now \u00e9 is UTF-16 for é so the data must be properly encoded to parse past \u00. So if your data was initially a string you can get the data from it like this.
NSString *text = #"<node>Ch\u00e9rie</node>";
//Important or the parser will stop after Ch
NSData *utf16encode = [text dataUsingEncoding:NSUTF16StringEncoding];
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:utf16encode];
