Firefox not displaying CP437

I am developing an application with a Web interface, that is connecting up to an old Cobol mainframe, that uses CP437. We only have one system to communicate with, so if possible I would rather not do any charset conversions, and just use CP437 throughout.

I have changed the headers sent out with the HTML to show CP437 (in both the Apache header, and the meta tag):

Content-Type: text/html; charset=CP437
...
<meta http-equiv="Content-Type" content="text/html; charset=CP437">

It works well in internet explorer, with £ signs displaying correctly (pounds sterling, in case that symbol doesn't traslate!).

However, in Firefox, I just get the question marks in their place. In the Web Developer menu, the encoding shows as ISO-8859-1, so it looks like Firefox just doesn't recognise the character set.

Does anyone know how to get these working together? Is there anywhere a list of the character sets that Firefox knows about?

One other thing that you could try is using CP850 which is pretty close to CP437. Some of the box characters differ but I don't think you're using them.

http://mxr.mozilla.org/mozilla-central/source/intl/locale/src/charsetalias.properties is a close approximation of the charsets Gecko knows about. CP437 is not in fact one of them.

It's a issue of the font the text is displayed with. Assuming windows as users OS you may set up your CSS to display all elements using the Terminal-font. 

*{font-family:Terminal !important;}
