Question

Android App that have a string papà (if I output it, i see: papà).

I send this string to a PHP script encoded as JSON and if I echo this string I read: pap�.

If I see in the database it stored as pap� (obviously).

If I write papà direclty in the database I read papà (obviously).

At this point I’m near sure that the problem is PHP, I tried with htmlentities and in the database I read pap&agrave.

I think you have all information for my problem. Any idea?

Edit to add code:

In Android I have string put in a map:

dati.put("tipo", sottoT);

after do the params for Json

ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();
    for (Map.Entry<String, String> entry : dati.entrySet()) {
        params.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
    }

        JSONObject json = jsonParser.makeHttpRequest(URL,
            "POST", params);

I send the Json:

 public JSONObject makeHttpRequest(String url, String method,
        List<NameValuePair> params) {

    // Making HTTP request
    try {

        // check for request method
        if(method == "POST"){
            // request method is POST
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params));

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();

In PHP I take the data from POST:

header('Content-type=application/json; charset=utf-8');
$array = array();
foreach ($_POST as $k=>$v) {
    $array[$k] = $v;
}

$v at this point is already wrong…

PHP Version 5.3.14

Just for your curiosity… i finally fix the problem. I miss to add th charset the db have to use so i put:
$conn = oci_new_connect($userDb, $pswDB, $urlDb, 'AL32UTF8');
instead
$conn = oci_new_connect($userDb, $pswDB, $urlDb);

So Android have:
httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));
In Php i have:
header('Content-Type: application/json; charset=utf-8'); (don’t know if this is important)

This is all..ty all for help
