charset definition problem

Hi,

I've a strange problem with my website html pages. My pages have charset defined in the page's header as "windows-1255" but sometimes explorer browsers take utf8 encoding. Then People see a white page because the browser can't display the page correctly. I tryed to add to the server in international support the alias charset cp1255 but is not defined by the server. i think that sometime explorer browsers fail to read the correct charset from the html page then it take the default explorer charset utf8 because the server send none default charset in HTTP header request. How can correct this problem? how can i define cp1255 as default encoding in my server?

thanks
