Thread: Eliminating Unicode Characters and Escape Characters from String

I want to fetch just 'My Actual String'. Is there any way to do so either by using any string built in method or Regular Expression ?

First, you should clarify where are these strings. Do you have a file (or any other character source) that contains literally '\' followed by 'u' followed by '2' etc... ? Or do you have a literal string in a Java source file like:

String s = "\u2029My Actual String\u2029";

In this last case, at runtime you don't have an "escape". The first and last chars are a single character with code 0x2029 (8233 in decimal). The "escape" is only in the source file!

So please, clarify.
