Java Resolve Response URLConnection Header Value

Question

I send http head request with URLConnection and got header value Content-Disposition Unreadable value like bellow.

Content-Disposition: attachment; filename="৩টি ধাপে সহজেই আতà§à¦¬à¦¬à¦¿à¦¶à§à¦¬à¦¾à¦¸à§€ হয়ে উঠà§à¦¨ | Motivational Video in Bangla.mp4"

How to resolve this text ৩টি ধাপে সহজেই আতà§à¦¬à¦¬à¦¿à¦¶à§à¦¬à¦¾à¦¸à§€ হয়ে উঠà§à¦¨ to ৩টি ধাপে সহজেই আত্ববিশ্বাসী হয়ে উঠুন

Answer 1

Your issue is that the response comes in a.. non-typical, Bengali encoding. I couldn't find the exact one, but seems to be something close to "Windows-1252".

Running the below code gives me the following output, having issues with some composite characters:

public static void main(String[] args) throws UnsupportedEncodingException {
    var source = "৩টি ধাপে সহজেই আতà§à¦¬à¦¬à¦¿à¦¶à§à¦¬à¦¾à¦¸à§€ হয়ে উঠà§à¦¨";
    var bytes = source.getBytes("Windows-1252");
    System.out.println("Expected: " + "৩টি ধাপে সহজেই আত্ববিশ্বাসী হয়ে উঠুন");
    System.out.println("Actual  : " + new String(bytes, StandardCharsets.UTF_8));
}

Expected: ৩টি ধাপে সহজেই আত্ববিশ্বাসী হয়ে উঠুন
Actual  : ৩টি ধাপে সহজেই আত�ববিশ�বাসী হয়ে উ� �ন

The solution may be to find the right decoder for this encoding of Bengali text so you can convert it to Unicode. Best of luck!
