URL's can not contain characters that are not in the ASCII character-set, such characters must be escaped.
URL 不能包含不在 ASCII 字符集中的字符，这些字符必须被转义。
Use stringByAddingPercentEncodingWithAllowedCharacterswith the character-set URLQueryAllowedCharacterSet
使用stringByAddingPercentEncodingWithAllowedCharacters与字符集URLQueryAllowedCharacterSet
NSString *path = @"http://fr.radiovaticana.va/news/2015/02/01/le_pape_fran?ois_à_sarajevo_le_6_juin_prochain/1121065";
NSString *escapedPath = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
NSLog(@"escapedPath: %@", escapedPath);
Output:
输出：
escapedPath: http://fr.radiovaticana.va/news/2015/02/01/le_pape_fran%C3%A7ois_%C3%A0_sarajevo_le_6_juin_prochain/1121065\
