Java is fun. The following is valid Java code: \u0070\u0075\u0062\u006c\u0069\u0063\u0020\u0020\u0020\u0020 \u0063\u006c\u0061\u0073\u0073\u0020\u0055\u00

  But that's not really surprising, it's each character as a unicode escape (see section 3.2 of the Java spec). It's possible in any language that allows escaped code points.

    Not surprising, yes. But what is silly is that the Unicode sequences are also interpreted in comments. /* Comment region begins. \u002a\u002f String s = "Comment was closed in the previous statement";

      That's a recipe for pure evil.

    Most languages only tend to allow them in string literals, or identifiers. Java is fairly unique in that it has a pre-processor that replaces those throughout the source code before actually compiling. Which means that a lot of benign-looking source code can have fairly surprising behaviour, such as exhibited in the polyglot where //\u000Afoo actually cancels the line comment.

    Oh man, if I had known that at my last job I could have had great fun with some of coworkers via my commits.
