Reading Unicode from textfile, displaying characters

Question

There is a textfile "readit.txt", which contains the following Unicodes:
\u672c\u8a9e\u6587\u5b57\u5217I'm reading this file and try to display it, expecting to see some Chinese characters on my screen.
try {
     fis = new FileInputStream(file);
     in = new InputStreamReader(fis);
     br = new BufferedReader(in);
     while((fileLine = br.readLine()) != null) {
          sb.append(fileLine + lineSep);
} catch(FileNotFoundException e) {
     e.printStackTrace();
} catch(IOException e) {
     e.printStackTrace();
System.out.println(sb.toString());Above code doesn't work. It just displays exactly whats in the file.
The weird thing is that it works well when doing this:
System.out.println("\u672c\u8a9e\u6587\u5b57\u5217");It will then output 本語文字列

The file has the character '\', then the character 'u', then the characters '6', '7', '2', 'c', etc. Those are just characters. BufferedReader has no way of knowing you want to interpret them as unicode escape sequences.
I imagine there's a method somewhere in the core API that will convert those sequences to their corresponding characters.

System.out.println("\u672c\u8a9e\u6587\u5b57\u5217");It will then output 本語文字列That's because the Java compiler, unlike BufferedReader, does parse unicode escape sequences.
