Description

The following UTF-8 sequence is not correctly handled and it is also handled differently if it is received as a payload from http or put into ballerina source code:

import ballerina/http;
import ballerina/io;

service / on new http:Listener(9090) {
    resource function post test(@http:Payload string payload) returns string {
        io:println("Explicit: Kolkāta");
        io:println("From Payload: ", payload);
        return payload;
    }
}

The resulting output in the console and in the API response look like this:

Explicit: Kolk─üta
From Payload: Kolk├ä´┐¢ta
