String literal = "\x6c\x69b/\x62\x2f\x6d\x69nd/m\x61x\x2e\x70h\x70";

7. Character Literals

Substitution of unnicode characters happens before the compiler sees the code, so when your code is compiled, it looks like this: char a=0; char b=1; char c=2; char y=9; System.out.println(""+a+b+c+y); Because 0x30... 0x39 are the ASCII for the ten decimal digits. But if you used (for example) \u0020, that's the ASCII space character, and you can see how you'd end up ...

The number of digits must be three or fewer, and the octal value cannot exceed \377, that is, only the first 256 characters can be specified with this notation.

13. Replacing unicode character literals with characters.

No, I just don't want to have to add another class to my code just to do a small task like this. And it's a great solution, but a much wider one, i.e. it does any regex and stuff. I just want a small few lines of code to do this for me (if that is possible)
