Module Xml_print.​Utf8

module Utf8 : sig..end

Utf8 normalizer and encoder for HTML.

Given a module pp functions produced by one of the functors in Xml_print, this modules is used as following:

let encode x = fst (Xml_print.Utf8.normalize_html x) in
    Format.printf "%a" (Html.pp ~encode ()) document

type utf8 = string
val normalize : string -> utf8 * bool

normalize str take a possibly invalid utf-8 string and return a valid utf-8 string where invalid bytes have been replaced by the replacement character U+FFFD. The returned boolean is true if invalid bytes were found

val normalize_html : string -> utf8 * bool

Same as normalize plus some extra work : It encode '<' , '>' , '"' , '&' characters with corresponding entities and replaced invalid html character by U+FFFD
