4.20: How do I unescape a string?

    It depends just what you mean by "escape". URL escapes are dealt with in
    perlfaq9. Shell escapes with the backslash ("\") character are removed


    This won't expand "\n" or "\t" or any other special escapes.


The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
