string - Is there a Java function which parses escaped characters?

Question

I'm looking for a built-in Java functions which for example can convert "\n" into " ".

Something like this:

assert parseFunc("\n") = "
"

Or do I have to manually search-and-replace all the escaped characters?

You can use StringEscapeUtils.unescapeJava(s) from Apache Commons Lang. It works for all escape sequences, including Unicode characters (i.e. u1234).
