Java - Evaluate String from String

Question

in my Java code I have this snippet:

String str = "\\u9601";

But I want it to be:

String str = "\u9601";

which represents a wide character.

Are there ways to do this?

Please help. Thanks in advance.

Supplementary:

Sorry for the badly-described question.

System.out.print("\u9601"); //this will display a Chinese character

I am currently request a webpage(URL) which response with a JSON. If dumped to Console using "System.out.print", the JSON will turn out to be 6 visible characters \, u, 9, 6, 0 and 1,but not a Chinese character in eclipse.

So actually what I want is are there APIs can convert "\\u9601" to "\u9601", since I can not hard code the Java source for the contents comes from website.

No, it doesn’t represent a “wide character”. It represents an abtract Unicode code point, U+9601. It is no wider than a LATIN CAPITAL LETTER A. Abstract code points have no width. — tchrist

I must be missing something, because if you wanted to use a unicode character escape you could delete a '\' from str. — wkl

@tchrist: I think he meant "wide" as in "double-byte". (Obviously, all string characters in Java are two bytes, so I think he really meant "non-ASCII.") — cdhowie

If you want it to be String str = "\u9601";, keep it that way!

Edit based on the updated question

The StringEscapeUtils.unescapeJava method in the Apache Commons Lang API should be of help:

    String str = "\\u9601";
    str = StringEscapeUtils.unescapeJava(str);
    System.out.println(str);

Sorry I can hard code the source, what I supplied is just an sample.

Indeed, the contents of the String variable is read from a website.
