That's right, it's a regression in 0.8.6, hopefully a "hotfix" will be 
deployed soon (fix is already in CVS).

The root cause is that we first transcode all documents to UTF-8, then pass 
the result of that to the XML parser for wellformedness checks (if the doc is 
XML).  That requires us to change encoding="..." in the XML declaration 
appropriately in the transcoded result before handing that doc to the XML 
parser, but unfortunately a bug snuck in 0.8.6 which broke this encoding-
munging operation.  And in this particular case the UTF-8-transcoded doc ended 
up being passed to the XML parser with the original encoding="windows-1250" 
intact and things went south from there :(
