  • Eclipse javascript character encoding

    - by Bardock
    Hi, I'd like to display some language specific characters from javascript but I can't. My app is a Java webapp and the front end is jQuery. All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly. When I want to display some text hardcoded in to the javascript file it's broken. I'm using Eclipse. In the JSP's header I use: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> I've tried this (charset in the script element) too: <script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script> In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. But when I try this: $.test = function(){ var s = "éééáááuuuu"; alert(s); } I get: éééáááűűűű The strange thing is that: When I try in a separate html file (in the same project), It's working: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type="text/css"> body {background: #c0c0c0;} </style> <script type="text/javascript"> $(document).ready(function(){ var s = "éááuuúúú"; $("#console").text(s); alert(s); }) </script> </head> <body> <div id="console"></div> </body> </html> Even if I DO NOT use any content type and page encoding settings. What is the problem? What shall I do? (I'm using Apache Tomcat integrated in Eclipse) Thanks in advance!
