Well, first you have to find out the encoding. Otherwise the data is just binary garbage to your and your programs.
I'd suggest to ask the ones that produced the data.
There are a few other possiblities, for example the text editor vim has a decent charset autodetection.
You can also try Encode::Guess, but you have to provide it with a list of possible encodings. Try to find out which encodings are used in japan on windows.
Once you know the charset, you can decode with (with decode from the module Encode) and work with it. |
