Special Accents and Characters in Ajax jQuery


I have a query that is done with Ajax request via jQuery. In the fields when I type a character as "ç" and send the request to the server, it is arriving with the character in another format. Ex: I type ç in the name field and it arrives in Action this way: ç. I'm using Struts 1.

Ajax calling code:

var request = $.ajax({
            cache: true,
            url: "/listagem",
            data:{  action: "ajax", 
                    page_num: page_num,
                    categoria: options.categoria,
                    estado: options.estado,
                    cidade: options.cidade,
                    especialidade: options.especialidade,
                    nome: options.nome_prestador,
                    bairro: options.bairro_prestador,
                    area_atuacao: options.area_atuacao,

I tried to put the following parameters and it did not work:

contentType: "application/json; charset=ISO-8859-1",
dataType: "json",

This one too:

 beforeSend: function( xhr ) {
   xhr.overrideMimeType( "text/plain; charset=x-user-defined" );

My JSP already has the following lines:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="utf-8" isELIgnored="false"%>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

When making Ajax requests that may have encoding problems (because they contain accents, tils, cedillas, or non-Latin characters (ie: Japanese, Arabic characters, etc.)), use the encodeURIComponent . This escapes the characters to something the server should be able to understand.


encodeURIComponent("ç"); // resulta em "%C3%A7"
encodeURIComponent("açaí"); // resulta em "a%C3%A7a%C3%AD"

For each string you are using that may contain special characters, do not use the string directly, but rather the return of encodeURIComponent on that string.

You need to change the page encoding to ISO-8859-1.

Every encoding of your call application should generally have the same charset.

I recommend that you use utf-8 as an unicode international standard.
