I want to replace string except first and last alphabet.
For example:
handsome -> h******e
한국어 -> 한*어
This is my code:
var final = string([]rune(username)[:1]
for i :=0l i <len([]rune(username)); i++{
if i >1 {
final = final + "*"
}
}

If you convert the string to []rune, you can modify that slice and convert it back to string in the end:
func blur(s string) string {
rs := []rune(s)
for i := 1; i < len(rs)-1; i++ {
rs[i] = '*'
}
return string(rs)
}
Testing it:
fmt.Println(blur("handsome"))
fmt.Println(blur("한국어"))
Output (try it on the Go Playground):
h******e
한*어
Note that this blur() function works with strings that have less than 3 characters too, in which case nothing will be blurred.
