HRESULT C00CE56E 'System Does Not Support the Specified Encoding' error message with MSXML

  • Article

This article helps you resolve the problem that HRESULT C00CE56E System Does Not Support the Specified Encoding error message with MSXML.

Original product version:   Microsoft XML
Original KB number:   304625

Symptoms

When you load a remote XML document from a Web server by using either XMLHTTP or XMLDocument::Load, you may receive the following error message:

HRESULT C00CE56E
System does not support the specified encoding.

This error is most prevalent when you use a Java-based middle-tier application framework.

Cause

As of version 2.6, MSXML passes all XML documents through Mlang.dll to verify their encoding. If Mlang.dll encounters a non-standard encoding string, it returns an error.

'ISO8859_1' is the canonical representation of the Latin-1 character encoding string in the Java language and class libraries. The standard that is defined by the Internet Assigned Numbers Authority, however, is 'ISO-8859-1', which is not an accepted alias.

Resolution

To resolve this problem, do either of the following:

  • Change the character encoding string in the relevant Java server environment from 'ISO8859_1' to 'ISO-8859-1'.

  • Use IXMLDOMDocument::get_responseBody to retrieve the data as a raw buffer of bytes. If you are developing the application in Microsoft Visual C++, you may define an HGLOBAL handle for your data and use CreateStreamOnHGlobal to make processing the data easier.
