#' @title
#' Reverse Each String
#'
#' @description
#' Reverses characters in every string.
#'
#' @details
#' Note that this operation is not very intelligent -- it just reverses
#' the order of all Unicode code points.
#' It may result in non-Unicode-normalized
#' strings and may give strange output for bidirectional strings.
#'
#' @param str character vector
#'
#' @return Returns a character vector.
#'
#' @examples
#' stri_reverse(c("123", "abc d e f"))
#' stri_reverse("ZXY (\u0105\u0104123$^).")
#' \dontrun{
#' stri_reverse(stri_enc_nfd('\u0105')) == stri_enc_nfd('\u0105') # A, ogonek -> agonek, A
#' }
#' @export
