[xmlsec] decrypting badly encoded xml

I am AES decoding some <EncryptedData> containing strings that was not utf-8 compliant.

When I decode the <EncryptedData> I get the error....

Entity: line 4: parser error : Input is not proper UTF-8, indicate encoding !
Bytes: 0xE2 0x3F 0x3F 0x41
<text>II The Way Forward�??A New Approach</text>
Entity: line 8: parser error : chunk is not well balanced

The call to xmlSecEncCtxDecrypt(encCtx, enc_node) fails because of this utf-8 problem. There are other tags encrypted between the <EncryptedData> tags (other than this one that has a problem) than I cannot recover because of this failure.  

Is there a way of forcing the xmlsec/libxml to ignore the utf-8 problem ?  
I have no control of the encrypted data so I cannot correct the original problem.
