The php code outputs iso-8859-1 and php sets that as the default characterse开发者_如何学JAVAt.

What is causing this problem? Am I using the wrong doctype?

Oh, and would any of this cause quirks mode in IE?

Thanks for your help.

The document is encoded in UTF-8. It has a byte order mark, smart quotes, and an ellipsis, all properly encoded in UTF-8. It begins with two byte order marks, which is invalid. You must remove one, and the validator also says that the presence of a BOM in a UTF-8 document may be confusing, so you may remove them both.

Since you’re outputting UTF-8, you must change the HTTP header to:

Content-type: text/html; charset=utf-8

Since you are missing that header, you force the browser to guess. Additionally, the meta tag must be changed to

<meta http-equiv="Content-type" content="text/html; charset=utf-8" />

for the same reason.

Your output starts with a Unicode byte order mark, encoded in UTF-8.

This is likely the first some bytes of your PHP file, or any PHP file included by your main file. Your editor may not even show them. Interpreted as ISO-8859-1 the start of the output looks like ï»¿ï»¿<!DOCTYPE html, which are even two byte order marks, one after each other.

As said by jleedev, either make sure your files are really encoded in Latin-1, or declare the encoding as UTF-8.
