In my UTF-8 text Perl script file, I have the following text (obtained by opening and reading another txt document):

$str = "F'252'r ('8364')"

Numbers in between the ' quotes are unicodes in decimal. For the above example, ü and € respectively.

What is the code required to produce a string so that the editor displays it as: “Für (€)”

I have tried using Encode::encode, Encode::decode, pack and unpack.
