asp:textbox displays question marks instead of Kanji/Japanese characters characters
<p>I have an aspx page which consumes a Siebel webservice and gets Kanji characters from Siebel on demand. This shows as a series of question marks in the aspx textbox. This cannot be a data error from the backend as the other applications get proper kanji characters from Siebel. Also, I have installed East Asian languages from control panel and added [ja-Jp] language under Languages tab of Internet Explorer 7. also, I have added 
    <strong>globalization requestEncoding="Shift-JIS" responseEncoding="Shift-JIS"</strong> 
to my web.config and have also tried changing 'Shift-JIS' to 'utf-8' in the above line, but no difference. I have also saved my aspx page and its code-behind pages with Unicode (utf-8 with signature) encoding, but find no change in the characters displayed in the textbox.</p>

<p>Please help.</p>
