val set_string_len : (String.t -> int -> int -> int) -> unit

Set which function is used to compute string length. Typically to be used with a unicode-sensitive length function. An example of such a function for utf8 encoded strings is the following (it uses the Uutf and Uucp libraries):

let string_leng s i len =
  Uutf.String.fold_utf_8 ~pos:i ~len
    (fun n _ c -> n+ max 0 (Uucp.Break.tty_width_hint c)) 0 s

Note that this function assumes there is no newline character in the given string.

since 0.3, this is also used in [printbox_unicode] to basically install the code above
