<div class="symptoms_section">

SYMPTOMS
In Windows Internet Explorer 7 or in Microsoft Internet Explorer 6, when you try to use POST method or the GET method to pass Form data in a Web page, you may experience one of the following symptoms.

Symptom 1
The POST method or the GET method may encode certain characters as Unicode numeric character references. For example, these methods may encode &#12354; 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.

Symptom 2
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:

Char:

Error: Unspecified error.

Code: 0

URL:

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.

<div class="cause_section">

CAUSE
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.
