HOTFIX: Problems may occur when you try to use POST method or the GET method to pass Form data in a Web page in IE7 or in IE6
The POST method or the GET method may encode certain characters as Unicode numeric character references. For example, these methods may encode あ as %26% 2312354%3B.
This problem may occur in Web pages that contain Japanese characters. Additionally, the Web pages are marked with a charset of windows-31j in the HTTP headers.
The POST method or the GET method cannot transmit Form data to the Web server. Additionally, you may receive a script error message that resembles the following:
Line: Line Number
Error: Unspecified error.
This problem may occur if the Form data contains Unicode-only characters at the start of a lone field. For example, the Form data may contain one of the following kinds of Unicode-only characters at the start of a lone field:
• A mixture of ASCII and Japanese characters.
• The character U+301C (tilde 〜) together with Chinese, Japanese, or Korean characters.
• The character U+3030 (tilde 〰) together with Chinese, Japanese, or Korean characters.
This problem occurs because Internet Explorer does not correctly use the code page for the required language when the Form data contains certain character combinations.
