Using strings.EqualFold Function

The strings.EqualFold() function reports whether s and t, interpreted as UTF-8 strings, are equal under Unicode case-folding, which is a more general form of case-insensitivity.

See the following example:

package main

import (
  "fmt"
  "strings"
)

func main() {
  fmt.Println(strings.EqualFold("HeLLO", "hello"))

  // It even works with Unicode.
  fmt.Println(strings.EqualFold("A̐É", "a̐é"))
}
