Steps to reproduce:
I have a html page as below with two input elements. First value is encoded using numeric character reference(NCR) and second value are two normal Chinese characters. The second characters is encoded using 4 bytes.
<html>
<head>
<title> New Document </title>
</head>
<body>
<input type="text" value="我��"/>
<input type="text" value="我

When you use numeric character references, HTML requires you to use a single character reference for the Unicode code point (𤭢 in this case) instead of encoding a surrogate pair as numeric character references.

Henri, do we need to file a bug on WebKit here if they're violating the spec?

AFAICT, WebKit and Opera aren't violating the spec. IE9 violates the spec, but it's been fixed in the latest mode of IE10. Hooray for specs and test suites.

Ah, indeed. I assumed that if the reporter was reporting the bug using Chrome then Chrome would have the "expected" behavior, but apparently not!
Thanks for your reply!
I only noticed that it automatically add user agent in description. I tested on FF10 but filed this bug using Chome.
I am wondering if there is any particular reason of using single character reference for one unicode code point?
Thanks

Yes, the reason being that character references represent Unicode codepoints and are encoding-independent...
