I have a problem with my site displaying as ANSI, while I save all my files in UTF-8 and put content type meta tag also as UTF-8 but the result pages are in ANSI. I don’t think it’s the issue of my server (which I don’t have access with its configurations) because I have other site in the same server but displaying correctly.
A live example might help because it’s a little too hard to tell from that description especially it you have saved the files as UTF-8 in the first place. What happens if you put one of your pages that ‘doesn’t work’ on the server ‘that works’ does it then work, and if so then you’ll know if it’s likely to be a server header issue.
