因项目需求，微信呢称中需要去掉特殊。直接上代码了。希望对大家有帮助

ios版：

const char* IosHelper::removeEmoji(const char* str){    std::string strLen = str;    NSString* username = [[NSString alloc] initWithBytes:str length:strLen.length() encoding:NSUTF8StringEncoding];    cocos2d::log("IosHelper::removeEmoji username0 = %s",str);    NSLog(@"IosHelper::removeEmoji username1 = %@",username);    //NSString *regex = @"^[a-zA-Z0-9_\u4e00-\u9fa5]+$";    NSString *regex = @"[\u0020-\u007e\u4e00-\u9fa5]";    //NSString *regex = @"^[a-zA-Z\u4e00-\u9fa5]+";    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];    NSString *temp = nil;    //NSLog(@"IosHelper::removeEmoji username = %d",[username length]);    for(int i = 0; i < [username length]; i++)    {        temp = [username substringWithRange:NSMakeRange(i, 1)];        //NSLog(@"i = %d char = %x str = %@",i, temp,temp);        if ([predicate evaluateWithObject:temp]) {            //NSLog(@"This character is OK");        } else {            NSRange range = NSMakeRange(i, 1);            username = [username stringByReplacingCharactersInRange:range withString:@" "];        }    }        NSString *withoutEmojiUsername = [username stringByReplacingOccurrencesOfString:@" " withString:@""];    NSLog(@"IosHelper::removeEmoji username2 = %@",withoutEmojiUsername);    const char* retStr = [withoutEmojiUsername UTF8String];    cocos2d::log("IosHelper::removeEmoji username3 = %s",retStr);    return retStr;}

android

 public static String RemoveEmoji(String str) { //String regEx = "[^A-Za-z0-9\u4e00-\u9fa5]"; String regEx = "[^\u0020-\u007e\u4e00-\u9fa5]"; Pattern p = Pattern.compile(regEx); Matcher m = p.matcher(str);  return m.replaceAll("").trim(); }
