Hi there!

I am running into a bit of a problem with Unicode. I am trying to make a game that will work in many languages, English, Greek, Japanese, Chinese etc.

So far so good. I have created a class that converts a String into unicode characters. For instance
String s = stringToUnicode("lie");
s=="\u0077\u0061\u0074";

I have also created a method that does the opposite. So if I say
String s = unicodeToString("\u0077\u0061\u0074");
then s == "lie";

However when I am trying to read the string "\u0077\u0061\u0074" from an XML (UTF-8) file, then there's no way on earth to convert it into a character. For some inexplicable reason it returns as a string and the escape \u characters cannot be dereferenced. For example \u0077 cannot be expressed as 1 character (char c = '\u0077') but it is returned as a string String s = "\u0077" and I have tried so many things but it seems impossible to make a character again!!

Any help please?

Ideally I am looking to convert this string "\u0077\u0061\u0074" into a string of actual characters. It works if I do it in a Java class, but it doesn't work if this string is returned from a file.

Thank you

What's wrong with just using Strings normally?

As Jimbo points out, Java Strings are already Unicode. Actually, since the Java char type is 16-bit, all text in Java should be Unicode. So, as I see it, you have two solutions:

First, you can use Unicode text files. This should allow you to read them from your Java programs just fine.

Second, you can rewrite your function to convert a sequence of bytes (not chars) into a Java String. This way, you can read it from the file if it is ASCII (but if the file is Unicode, you've got problems unless you employ some logic to check for this somehow). Note I say ASCII here instead of UTF-8; the latter is a more complex format where characters range from one to four bytes (more details here).
