Question

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?

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
}

My resteasy-jaxrs-3.0-beta-2 is running on Tomcat 7.0.

Thank you!

This is not about resteasy or jax-rs mate.

There are several things you may want to look into:

1. If the data is from DB, then you need to make sure data in DB it is encoded correctly.
2. Your JVM environment is encoding using utf8
3. It could be an issue of IDE, because IDE and your tomcat might running on different
   configurations.
