While this approach will get the right answer most of the time, and maybe all of the time in practice, it will not always work in general. Consider a string containing the characters "X\\n". The pair of backslashes should be rendered as a single backslash, and the 'n' as a literal 'n', with no linefeed. I don't think you can get that result with simple string replacements. For further perversities, consider "X\\\n", "X\\\\n", and so forth. To do the job correctly, there's no way to avoid traversing the string character by character, responding to backslashes as you find them (unless of course such a function is already available). Such a function is not hard to write, just a little tedious. The main issue is input like "X\z", where "\z" has no special meaning. Do you render it as "X\z" or "Xz"? Or issue an error message?
