I personally find it a smart idea to represent chinese characters as an HTML entity such as "能" if they are entered into say an iso-8859-1 form.
However, since this is apparently undefined as per the standards, I guess one should at least warn a user before such form input will be submitted (see also )

This is a mass search for bugs that are in the Firefox General component, are UNCO, and have not been changed for 1000 days and have an unspecified version. 

Reporter, can you please update to Firefox 3.6.10, create a fresh profile, http://support.mozilla.com/en-US/kb/managing+profiles, and test again. If you still see the bug, please update this bug. If the issue is gone, please set the resolution to RESOLVED > WORKSFORME.

If a user enters characters into a form that does not correspond to the declared character set, it is important to warn them about the issue. One way to do this is to provide an error message that informs the user that the entered characters are not valid and do not meet the required format.

For example, if the form requires only alphanumeric characters and the user enters a special character, the error message could say something like: "Invalid input. Only alphanumeric characters are allowed in this field."

It is also a good idea to highlight the specific field where the error occurred so that the user can easily identify and correct the mistake. This can be achieved by changing the color or border of the field, or by displaying an icon or text next to it. https://www.mybpcreditcard.us/

Providing clear error messages and highlighting the specific field can help improve the user experience and reduce frustration, while also ensuring that the data entered into the form is accurate and consistent with the desired format.
