There is a dedicated DecodeRune function :

func DecodeRune(p []byte) (r rune, size int)

DecodeRune unpacks the first UTF-8 encoding in p and returns the rune and its width in bytes. If the encoding is invalid, it returns (RuneError, 1), an impossible result for correct UTF-8.

So you just have to import "unicode/utf8" and do 

r, _ := utf8.DecodeRune(key)
