HTML字符串中无法识别项目符号

Question

我有一个字符串：

NSString *str1 = @"\u2022 You were held in custody for a longer 
                   period of time than may have been necessary.";

我正在使用以下代码将其转换为HTML字符串：

- (NSString *)HTMLString {
    NSDictionary * const exportParams = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType};
    NSAttributedString *attributed = [[NSAttributedString alloc] initWithString:str1];
    NSData *htmlData = [attributed dataFromRange:NSMakeRange(0, attributed.length) documentAttributes:exportParams error:nil];
    return [[NSString alloc] initWithData:htmlData encoding:NSUTF8StringEncoding];
}

但是HTML字符串中没有显示项目符号。它显示?而非子弹点。请告诉我任何解决方案。

请尝试以下代码 -

- (NSString *)HTMLString {
    NSDictionary * const exportParams = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType};
    letterString = [letterString stringByReplacingOccurrencesOfString:@"\u2022" withString:@"•"];
    NSAttributedString *attributed = [[NSAttributedString alloc] initWithString:letterString];
    NSData *htmlData = [attributed dataFromRange:NSMakeRange(0, attributed.length) documentAttributes:exportParams error:nil];
    return [[NSString alloc] initWithData:htmlData encoding:NSUTF8StringEncoding];
}
