Before I go and write my own FSM I was wondering if anyone knew what class might be used to convert those neat little escape sequences like \n and \245 in strings.

I did have a neat little function that took care of \n and \t, but then the customer began to talk and I realized that I needed something more. Extending my little program does not work well since it just used the String.Replace function with a fancy little RegEx (?<=^|[^\\])\\[n].

But this method has a lot of problems when you try to do more complex replacements.

I searched/am searching the java API but so far no luck.

So, does anyone know a class that does these replacements?

That was not exactly what I had in mind. In the end I think I will just write my own. Of course, as soon as I am done someone will point out a simple 1 line bit of code that does it... oh well.

Since I never found an API class for this I went ahead and did my own. For my application I have a version that just takes in a String and does the replacements, but I went the extra step of creating a FilterOutputStream version that I have posted as a snippet.

I figure that this might be helpful to someone. If nothing else it is an example of a Finite State Machine -- although not a terribly interesting one.

here it is.

Note: I am not too sure this works correctly with the whole unicode character bit.
