My Android app communicates via HTTP Post with a PHP server. I add to the HTTP request following parameter:
nameValuePairs.add(new BasicNameValuePair("text", message));
message is a String and contains the symbol €
On the server PHP is running and gets the request. Unfortunatelly the € symbol is automatically converted to ? symbol. All other symbols are working like "ä, ü, $, ß
On Android I have set no encoding:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://server.com/test.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
On the PHP site I have also nothing specified. Here the code:
<?php
mysql_connect("blablaost.com", "blabla", "blabla") or die(mysql_error());
mysql_select_db("asfd") or die(mysql_error());
$mysqldate = gmdate( 'Y-m-d H:i:s');
$language = (int) $_REQUEST['language'];
mysql_query("blabla ... .$_REQUEST['text']. ")
or die(mysql_error());
mysql_close();
?>
$_REQUEST['text'] contains the € and it gives me a ?

The second construction parameter of UrlEncodedFormEntity is the transmit encoding. Replace with:
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
Also, make sure that the Web page that displays the value reports a charset to the browser and conforms to that charset. To report the charset to the browser, use either
header("Content-Type: text/html;charset=UTF-8", true);
in PHP, or
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
element under HTML's <head>. The former trumps the latter, if both are provided.
The actual encoding that the PHP file has (i. e. the encoding of non-ASCII characters in it) has to match the one PHP file claims as its Content-Type. Depending on your PHP editor, there may be different ways to set the encoding of the file. In Visual Studio, for example, there's a "Save with encoding" command.
EDIT re: unrelated issue:
To remove PHP magic quotes, I use the following function:
function deq($s) //Stands for "dequote"
{
if($s == null)
return null;
return
get_magic_quotes_gpc() ?
stripslashes($s) : $s;
}
And then instead of $_POST["xxx"], I use deq($_POST["xxx"]) where appropriate. Since the server settings may change (and the server itself might change if you migrate), the dequote function must take the current value of the setting into account.
