Character encoding after window.open()

[stup]

Hi!

I have a small javascript snippet that does the following:

// an entire html document is in here
data = "\u003c!DOCTYPE html PUBLIC \u0022-//W3C//DTD XHTML 1.1 Strict//EN\u0022\n  ...."; 
 
newwin = window.open("", "outputwin", "");
newwin.document.write(data);
newwin.document.close();
 

Now, in the data variable, the character encoding is set to be UTF-8 using a meta http-equiv tag. Same for the page that contains this script.

When I look at the character encoding in the Firefox (2.0.0.3) "View Page Info" dialogue box, it tells me the following:

The original page has an Encoding of UTF-8 and the Content-type is text/html; charset=utf-8

The new page, however, has an Encoding of ISO-8859-1 but the Content-type is shown as text/html; charset=utf-8.

This is the case when there are non-ISO-8895-1 characters present although they are correctly displayed.

So...

* Is this something to be worried about?

* Is this something I can address in the javascript? (is there an optional argument to document.open that specifies the charset? I can't find one!)

* Is this instead a Firefox bug?

All thoughts and ideas appreciated.

Follow-up: saving the source of the file in Firefox and looking at it in a hexeditor, it looks like it's actually UTF-16/UCS-2.

Even more strange?

Sorry to jump into your thread, but hey, free bump back up to the top!

I'm having the same problem but trying to use IBM850 character set. On a normal page, I send the following line in the header information (i.e. before the html tag):
Content-type: text/html; charset=IBM850

I can't do this when using Javascripts window.open. Firefox shows the encoding of a javascript popup window to be UTF-8. I've already tried adding the following line inside the HTML that is written to the javascript window:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=IBM850">

This has no effect though. Any non-ASCII IBM850 characters are displayed wrongly in the popup window.
