Solution: iis7: In the multi-byte target code page, there is no character that can be mapped to this UNICODE character. (Exception from hresult: 0 × 80070459)

When we use Asp.netProgramWhen migrating data to iis7, if there are unencoded Chinese characters in the page cookie, the IIS kernel reports an error,

The error message is as follows:

In multi-byte targetsCodePage, there is no character that can be mapped to this UNICODE character. (Exception from hresult: 0x80070459)

The English error message is as follows:

No mapping for the Unicode character exists in the target multi-byte code page

 

This is true after the unit test. It is not tested in IIS6. I wonder if this will happen.

 

Solution: store the cookie value after URL encoding.

Httpcookie cookie = New Httpcookie ( "Username " , Httputility. urlencode (username ));
Cookie. expires = datetime. Now. addmonths ( 1 );
Response. appendcookie (cookie );
