如何在RESTeasy中将编码设置为UTF-8?

我在RESTeasy中编码字符串时遇到问题.问题是中文字母或任何其他非拉丁字符无法正确显示.如果我尝试将它们打印出来(或作为响应发送)，我会收到"??????"反而. 我相信RESTeasy中的默认编码是us-ascii.您知道如何将其更改为UTF-8吗?也许对此问题还有另一种解决方案?

I have a problem with encoding strings in RESTeasy. The problem is that chinese alphabet or any other non-latin characters are not displayed properly. If I try to print them out (or send as response) I get "?????" instead. I believe that default encoding in RESTeasy is us-ascii. Do you know how to change it to UTF-8? Maybe there is another solution to this problem?

这里是我的代码的一小段内容:

Here is a short passage from my code:

@POST
@Path("post")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public String uploadData(@MultipartForm DataUploadForm uploadForm) {

...

//the code below is just for the purpose of presentation

String text = "some non-latin alphabet signs here"
System.out.println(text);  // "??????" is printed out

return text; //"??????" is returned
}

我的resteasy-jaxrs-3.0-beta-2在Tomcat 7.0上运行.
