I needed to replace a specially coded tokens with their unicode
representations. strings.NewReplacer made it clean and easy.
first, you pass to strings.NewReplacer a string array literal made up of
old, new string pairs, like so
var logicalReplacer = strings.NewReplacer(
"%and", `∧`, //LOGICAL AND
"%or", `∨`, //LOGICAL OR
"%cap", `∩`, //INTERSECTION
"%cup", `∪`, //UNION
)
then you call Replace() on it passing the text you want to process:
func main() {
fmt.Println(logicalReplacer.Replace("x and y"))
fmt.Println(logicalReplacer.Replace("x cap y"))
}
