PHP and Java encoding issues

Question

I recently wrote a webservice that runs as a Java application (probably not the best idea, but I'm more fluent in Java than in other languages like PHP or English :p). The Java application simply outputs the JSON data to System.out.

And then I wrote a tiny PHP script that uses the Java application.

Here is my PHP script :

ob_start('ob_gzhandler');
header("Content-Type: application/json; charset=UTF-8");
passthru("java -jar webservice.jar ");

The issue is that every special char (like "é") is output as "??"

Any idea of what I could try to fix that encoding issue ?

Thanks

EDIT : when I run java -jar webservice.jar in a shell, I have no encoding issue

In a shell command line I have no encoding issue (edited post to add this fact). In browser (or in my mobile client app) the issue appears, that's why I believe it's related to the php script — Estragon

@Estragon Are you sure the output is actually UTF-8 encoded? What happens when you change the encoding to Latin in your browser? — madflow

The PHP manual states, that passthru should be used mainly for binary data output. Try using system() maybe? — madflow

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

Sounds like you need to make sure you are handling the double byte characters correctly :)

I solved my problem by adding -Dfile.encoding=UTF8to my java call :

java -Dfile.encoding=UTF8 -jar webservice.jar

I guess there may be a better solution but it solved my problem so :)

Encoding is a problem that covers a lot of variables: operational system, app, bd etc.

Try to follow this: http://www.phpwact.org/php/i18n/utf-8
