When you try to use a session.codepage or @codepage directive in an Active Server Pages (ASP) page that is hosted on a Microsoft Internet Information Server (IIS) 4.0 Web server, the following error message may occur:
Active Server Pages error 'ASP 0203' Invalid Code Page /ProjectName/PageName.asp, line 1 The specified code page attribute is invalid.
If the ASP page is hosted on a Microsoft Internet Information Services 5.0 Web server, the following error message may occur:
Active Server Pages, ASP 0203 (0x80004005) The specified code page attribute is invalid
Code pages have been disabled for Internet Information Server 4.0 since Windows NT 4.0 Service Pack 4 because of truncation issues, which caused characters larger then 2 bytes to be truncated. This created a problem with some double-byte character sets (DBCS), such as Japanese, that have characters that extended beyond 2 bytes in size. In Internet Information Services 5.0, the utf16(1200) and unicodeFFFE(1201) code pages are disabled.
This behavior is by design.
To work around this issue, try the following:
If you are running Internet Information Server 4.0, upgrade to Internet Information Services 5.0. The following Unicode code pages are valid in Internet Information Services 5.0:
65000 - utf-7 65001 - utf-8
Instead of using Unicode, develop your Web site to be language-specific by using the appropriate character set in the client HTML. For a complete list of available HTML character sets and ASP code pages, see the following Microsoft Web site:
<%@ Language=VBScript CODEPAGE=932%><%Session.Codepage=932%><!-- This is for the Japanese code page --><HTML><HEAD><META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0"><META HTTP-EQUIV="Content-Type" CONTENT="text/html; CHARSET=shift_jis"></HEAD><BODY></BODY></HTML>
Steps to Reproduce Behavior:
Host an ASP page on a computer that is running Internet Information Server 4.0 or Internet Information Services 5.0.
Add the following code to the page:
<%@ Language=VBScript codepage=1200%><!-- This is for the UTF 16 code page --><HTML><HEAD><META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0"><META HTTP-EQUIV="Content-Type" CONTENT="text/html; CHARSET=utf16"></HEAD><BODY></BODY></HTML>
Save the page, and then view the page in the browser.
