makes "d"s turn "p"s "d"s again. there method @ same time?

i appreciate answer. thanks.

iterate on characters 1 one, building new string in stringbuilder or stringbuffer, don't change original string reference got.

edit - sample code

here sample code, don't remember vb syntax suppose below correct:

dim text string = "hello world"  dim sb new stringbuilder()  each c char in text     if c = "a" sb.append("ɐ")     if c = "a" sb.append("∀")      ' ...     ' ...     ' rest of cases same way     ' ...  next  text = strreverse(sb.tostring())
