Making sure you are encoding your strings as UTF-8 in Java should solve the trick.

Encoding With Commons-Codec

<dependency>
    <groupId>commons-codec</groupId>
    <artifactId>commons-codec</artifactId>
    <version>1.14</version>
</dependency>

String rawString = "Welcome to Progress - Image Film"; 
byte[] bytes = StringUtils.getBytesUtf8(rawString);
 
String utf8EncodedString = StringUtils.newStringUtf8(bytes);

What is UTF-8?

UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte code units.

@keshava219 Please try out with the below properties in the servlet, while making the request to the api to return the response.

    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
    con.setRequestMethod("GET");
    con.setRequestProperty("accept-charset", "UTF-8");
    con.setRequestProperty("content-type", "application/x-www-form-urlencoded; charset=utf-8");

Hope this helps!

Thanks

@keshava219 What is your content type? is it "application/x-www-form-urlencoded"?

Hi @keshava219 , This is because of characters encoding/decoding in a API response( as a matter of. fact, any string-based response).

I saw your response is coming from BufferedReader, so now convert BR to String & then pass into below method to get properly decoded values.

please use following code after you receive response & pass each string here to get proper values.

~Aditya.Ch

import java.net.*;
private String allowSplChars(String incomingString) {
        String encodedValue = null;
        try {
        encodedValue= URLEncoder.encode(incomingString.trim(), "UTF-8");
        } catch (UnsupportedEncodingException uee) { 
        	log.error("UnsupportedEncodingException", uee);

        }
         return encodedValue;
	}
