It works with runes as long as is it possible.

func Alpha(s string) bool {
    for _, v := range s {
        if ('Z' < v || v < 'A') && ('z' < v || v < 'a') {
            return false
        }
    }
    return true
}

usage

package main

import "gopkg.in/alioygur/is.v1"
import "log"

func main()  {
    is.Email("jhon@example.com") // true
    is.Numeric("Ⅸ") // false
    is.UTFNumeric("Ⅸ") // true
