Hi Sasa,
The parser is working as expected. A bug fix in the ASCIIReader now
rejects any bytes that are not valid US-ASCII. This is in accordance with
the XML rec (http://www.w3.org/TR/REC-xml#charencoding): "It is a fatal
error if an XML entity is determined (via default, encoding declaration,
or higher-level protocol) to be in a certain encoding but contains octet
sequences that are not legal in that encoding."
Since your document is labeled US-ASCII and contains non ASCII bytes, the
document isn't well formed. The ASCII range is Unicode 0-127. Any bytes
outside that range are not members of US-ASCII. The character you intended
to include in your document is part of Latin-1. If you want to correct
your document, one way is to change the encoding attribute to ISO-8859-1.
