Golang : Frobnicate or tweaking a string example

A simple example of how to frobnicate(tweaking) a string with UTF-8 characters. Useful in obscuring plain text in embedded in executable binary file if you do not want the text to be visible to someone viewing your executable file with a hex editor. To achieve that, first frobnicate the text first into a obfuscated(frobnicated) text and then use the frobnicate function again on the obfuscated text during runtime to convert to readable text.

Here you go!

 package main

 import (

 // frobnicate/tweak a string
 func frobnicate(input string) string {
  var result []string

  for _,i := range input {
 switch {
 case unicode.IsSpace(i):
 result = append(result, " ")
 // uncomment to frob the digits
 //case unicode.IsNumber(i):
 // result = append(result, string(rune(i)))
 case utf8.ValidRune(i):
 result = append(result, string(rune(i) ^ 42))


  return strings.Join(result,"")

 func main() {
  text := "жѳМѭњЂЯёЧВ 一二三 handle alphabets = ขอพฮศโำฐเฦ abc世界你好123 ペツワケザユプルヂザ"

  fmt.Println("Invertible test:")
