When you need to prevent quick grepping in Java, you can also take advantage of the fact that unicode escapes can occur everywhere in a java file, not only within quotes. So you can declare an int by writing “\u0069\u006e\u0074 \u0069 = 1;” (equivalent to “int i = 1;”)

It's important to use this sparingly. When grepping is obviously broken, the adversary will adapt, most likely by writing a script to rewrite the Unicode, then it's back to business as usual.

On the other hand, if grep has a 95% success rate, the adversary may well never notice, and build his or her mental model of the program on flawed understanding. That's when the real fun begins.

This is why I turn on spell check in Idea and fix spellings.

Why not \u0069\u006e\u0074\u0020\u0069\u0020\u003d\u0020\u0031\u003b ?

An IDE should tackle this w/o any problem.
