Multipart form-data with cyrillics are replaced by '?'

Here is my method for example:

    public void postSomething(){

        RestAssured.config = RestAssured.config()
                .encoderConfig(encoderConfig().defaultContentCharset("UTF-8"))
                .encoderConfig(encoderConfig().defaultCharsetForContentType("UTF-8", "multipart/form-data"))
                .multiPartConfig(multiPartConfig().defaultCharset("UTF-8"))
                .decoderConfig(decoderConfig().defaultContentCharset("UTF-8"))
                .decoderConfig(decoderConfig().defaultCharsetForContentType("UTF-8", "multipart/form-data"));

        String response = given().log().all()
                .multiPart(new MultiPartSpecBuilder(Charsets.UTF_8).build())
                .config(RestAssuredConfig.config().httpClient(HttpClientConfig.httpClientConfig()
                        .httpMultipartMode(HttpMultipartMode.BROWSER_COMPATIBLE)))
                .contentType("multipart/form-data; charset=UTF-8")
                .multiPart("cyrillic", "ЙЦУКЕН фывап")
                .when()
                .post("http://df4d777e.ngrok.io/123")
                .then().log().all()
                .assertThat().extract().response().body().asString();
    }

Console logs looks fine i guess

but on server it looks like this

Windows 10 Rest-assured 4.1.2

Is there anything i’m doing wrong?

Try this .multiPart(new MultiPartSpecBuilder(“ЙЦУКЕН фывап”).controlName(“cyrillic”).charset(StandardCharsets.UTF_8).build())

[sleepstream]

Try this .multiPart(new MultiPartSpecBuilder(“ЙЦУКЕН фывап”).controlName(“cyrillic”).charset(StandardCharsets.UTF_8).build())

Thanks a lot!! It’s worked for me!
