Decoding a string from the non-Unicode charset

A lesser-known fact is that all content in .go files is encoded in UTF-8. Believe it or not the Unicode is not, the only charset in the world. For example, the Windows-1250 encoding is widely spread across Windows users.

When working with non-Unicode strings, you need to transcode the content to Unicode. This recipe demonstrates how to decode and encode the non-Unicode strings.

How to do it...

1. Open the console and create the folder chapter02/recipe08.
2. Navigate to the directory.
3. Create the file win1250.txt with content Gdańsk. The file must be encoded in the windows-1250 charset. If you are not sure how to do that, just jump to step 6 and after you complete step 7, which will create the windows-1250 encoded file, you can rename the out.txt file and go back to step 4.
4. Create the decode.go file with the following content:

        package main

        import (
          "fmt"
          "io/ioutil"
          "os"
          "strings"

          "golang...
