How can see a string's unicode?

Hello, if I have a string A, how I can see the string's unicode? say,
display the String with format: "\u611F\u5192";

Currently I have a string A, which I don't know the encoding, but if I
display that string in the firefox browser, it is just some strange
letters, like this "æå". Actually is should display some meaningful
chinese characters, like "感冒"。

Can any one tell me how to convert the string A into unicode format
and let it display correctly in the browser?

Thanks a lot!

Just tell the browser it is UTF8

HTTP:
Content-Type: text/html; charset=utf-8

HTML:
<META http-equiv=Content-Type content="text/html; charset=UTF-8">

What you are asking in how to convert a String to char[]. From there
you want to dump each char in hex, and prefix a decorative \u

If you mean a Java String, then the String A is in Unicode, represented
in the API as UTF-16 code units.

but if I

Usually this is a combination of font choice and charset declaration.
Make sure you 1) declare the charset encoding of the HTML file and
generate the appropriate character code units for the HTML, and 2)have a
font that can contains glyphs for the Chinese characters.

The String A is already a Unicode encoding -- UTF-16. Use the
String#getBytes method to get a byte[] in a different encoding.

public static String encode(String s) {
StringBuffer sb = new StringBuffer("");
for(int i = 0; i < s.length(); i++) {
char c = s.charAt(i);
if((c >= 0) && (c <=255)) {
sb.append(c);
} else {
String hex = Integer.toHexString(c);
sb.append("\\u" + "0000".substring(hex.length(), 4) + hex);
}
}
return sb.toString();
}
