如何使用go在Windows控制台中正确输出字符串？

Question

I have a exe in go which prints utf-8 encoded strings, with special characters in it.
Since that exe is made to be used from a console window, its output is mangled because Windows uses ibm850 encoding (aka code page 850).

How would you make sure the go exe print correctly encoded strings for a console windows, ie print for instance:

éèïöîôùòèìë

instead of (without any translation to the right charset)

Since 2016, You can now (2017) consider the golang.org/x/text, which comes with a encoding charmap including the ISO-8859 family as well as the Windows 1252 character set.

See "Go Quickly - Converting Character Encodings In Golang"

r := charmap.ISO8859_1.NewDecoder().Reader(f)
io.Copy(out, r)

That is an extract of an example opening a ISO-8859-1 source text (my_isotext.txt), creating a destination file (my_utf.txt), and copying the first to the second.
But to decode from ISO-8859-1 to UTF-8, we wrap the original file reader (f) with a decoder.

I just tested (pseudo-code for illustration):

package main

import (
    "fmt"

    "golang.org/x/text/encoding"
    "golang.org/x/text/encoding/charmap"
)

func main() {
    t := "string composed of character in cp 850"
    d := charmap.CodePage850.NewDecoder()
    st, err := d.String(t)
    if err != nil {
        panic(err)
    }
    fmt.Println(st)
}

The result is a string readable in a Windows CMD.
