can not use the XSV because of encoding

Hello xmlschema-dev,

  How can i use XSV with other encodings?

  I use xml documents with header:
  <?xml version="1.0" encoding="windows-1251" ?>

  But the answer is

<?xml version='1.0'?>
<xsv xmlns="http://www.w3.org/2000/05/xsv" crash="true" instanceAssessed="false"
     target="file:///C:/file.xml"
     version="XSV 2.8-1 of 2004/07/01 13:14:57">
  <bug>validator crash during target reading</bug>
  <XMLMessages>
Error: Unknown declared encoding windows-1251
 in unnamed entity at line 1 char 44 of file:///C:/file.xml
Error opening source
</XMLMessages>
</xsv>
