Question

Arabic characters in ASP.NET

Asked by: cip

This very simple ASP file prints the word "presentation" in arabic:
<html>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1256">
<body><div id="divtext">
    <% Response.Write("ÇáÚÑÖ") %>
</div></body>
</html>

This very simple ASPX file prints unreadable characters:
(testarabic.aspx)
<%@ Page Language="C#" CodeFile="testarabic.aspx.cs" Inherits="testarabic" %>
<html>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1256">
<body>
    <form id="form1" runat="server">
    <div id="divtext" runat="server">
    </div>
    </form>
</body>
</html>
(testarabic.aspx.cs)
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class testarabic : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
    divtext.InnerHtml = "ÇáÚÑÖ";
  }
}

I have tried in every way to get arabic characters (changing globalization settings, saving the source files in ascii and unicode) without success. What's the way?

Do your really have to use windows-1256? Just sticking with UTF-8 is so much more convenient.


Well, there are quite a few places where encoding comes into play. Have you made the change in web.config?
<globalization requestEncoding="windows-1256" responseEncoding="windows-1256" />


Using Character Encoding in ASP.NET

Hello Dhaest,

I have to use windows-1256 because I have a full database of windows-1256 encoded characters. Those characters were used by my old ASP application which is now being converted to ASPX. At the moment I can't think about any method which quickly converts those characters to unicode, but that would be another good solution to come out from this problem.

I have tried the web.config changes you suggested but I keep getting unreadable characters.

 

by: digitalZoPosted on 2007-09-24 at 02:22:34ID: 19947163

Try this in the web.config:

< globalization
    fileEncoding="utf-8"
    requestEncoding="utf-8"
    responseEncoding="utf-8"
    culture="ar-EG"
    uiCulture="ar-EG"
  />

and in the <body> or <html> tag, type this:
<body dir="rtl">
OR
<html dir="rtl">

 

by: cipPosted on 2007-09-24 at 06:01:27ID: 19948010

None of your suggestions really helps, unfortunately. I have tried to change the web.config as digitalZo said, but now I get the characters exactly as written: "ÇáÚÑÖ".

Also I have tried to browse the links provided. The first one from Dhaest from codeproject gave me some clues, I have tried to implement this method:
public static string windows1256_unicode(string src)
{
  Encoding iso = Encoding.GetEncoding("windows-1256");
  Encoding unicode = Encoding.UTF8;
  byte[] isoBytes = iso.GetBytes(src);
  return unicode.GetString(isoBytes);
}

then in Page_Load::

...
divtext.InnerHtml = CEncoding.windows1256_unicode("ÇáÚÑÖ");
...

This should convert windows-1256 characters to unicode but I still get everything unreadable. The other links assume I have unicode characters in my db, which is not my current situation.

Save the page with 'unicode 1200'

 

by: cipPosted on 2007-09-25 at 01:36:44ID: 19954144

Saved both files (aspx and aspx.cs) with unicode 1200, but I still get the characters as written: "ÇáÚÑÖ".

Was any of you able to print arabic characters using my 2 small sample files?
Thanks

<<Was any of you able to print arabic characters using my 2 small sample files?>>

I tried your example. It was giving me the same problem as yours. I could be mistaken, but I think it was because I had defined the Arabic word as:
divtext.InnerHtml = "ÇáÚÑÖ";

Therefore, what I did was, I chose an Arabic word [the one given in the MSDN]: .'D@@@@/ and defined it:
divtext.InnerHtml = ".'D@@@@/";

AND SAVED the page as 'Unicode 1200'. It worked!

If I saved the page as Arabic-----, the output was in unreadable format. I did not add anything. Not even the globalisation in web.config. Just pasted your code and replaced the word with Arabic and saved the page as 'UNICODE 1200'.

I'm not sure whether this is what you want, but try it.

^Looks like this page is not encoded for Arabic characters either.

 

by: cipPosted on 2007-09-26 at 01:16:58ID: 19961332

Thanks digitalZo,

The problem is that I have a database full of "ÇáÚÑÖ" characters, since the old ASP version of my application did a perfect work with them and the meta tag "charset=windows-1256".

I can solve my problem either making my new ASP.NET application print arabic characters or finding a way to convert all my old windows-1256 characters stored in the database into your new working set.

Here is the answer:

http://support.microsoft.com/kb/893663/en-us

And in particular:
"We can also make ASP.NET behave like ASP if we need to. To make this occur, we need to set the responseEncoding and requestEncoding to windows-1252 (a more complete encoding than iso-8859-1), and use the Response.Charset property to display the text correctly. This works because windows-1252 is a single byte encoding scheme, and does not modify any bytes that are added to the buffer."

So, setting responseEncoding and requestEncoding in my web.config to "windows-1252" and then setting Response.Charset = "Windows-1256" in my page worked like a charm.
