Print string literal unicode as the actual character

Question

In my Java application I have been passed in a string that looks like this:

\"\\u00a5123\"

When printing that string into the console, I get the same string

Answer 1

I wrote a little program:

public static void main(String[] args) {
    System.out.println("\u00a5123");
}

It's output:

¥123

i.e. it output exactly what you stated in your post. I am not sure there is not something else going on. What version of Java are you using?

edit:

In response to your clarification, there are a couple of different techniques. The most straightforward is to look for a "\u" followed by 4 hex-code characters, extract that piece and replace with a unicode version with the hexcode (using the Character class). This of course assumes the string will not have a \u in front of it.

I am not aware of any particular system to parse the String as though it was an encoded Java String.
