How to display 🔴 in JLabel or java

Question

I am trying to figure out how to display 🔴 in java. I am able to convert unicode to show so if I could convert 🔴to unicode then I would be set. I was thinking I could just make a big check list but figure that would cause alot of strain to check.

I am trying to show 🔴, but the API call gives me 🔴. My question is, how do I change 🔴 to the red circle other then finding the Unicode string for it.

This is what the symbol looks like 🔴

Code to format json

private static String getStringFromInputStream(InputStream is) {

    BufferedReader br = null;
    StringBuilder sb = new StringBuilder();

    String line;
    try {

        br = new BufferedReader(new InputStreamReader(is));
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }

    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (br != null) {
            try {
                br.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    return sb.toString();

}

Answer 1

It looks like you're looking at the characters with an editor in which you haven't specified the correct character encoding / set.

To use smybol that String in Java, try:

String text = "\uD83D\uDD34";
JLabel label = new JLabel(text);

Source of the unicode escapes: https://www.htmlsymbols.xyz/unicode/U+1F534

(It may still be that your font doesn't have the character, in which case it will probably look like a question mark - better than 4 strange accented characters, probably)

Answer 2

There still remains one problem: new InputStreamReader(is) uses the default encoding the program runs on. I would expect the fixed encoding of the is : new InputStreamReader(is, "UTF-8")
