According to the docs, Expat unserstands the name US-ASCII, which is
also the preferred name used by IANA. Expat does not try to understand
all IANA aliases for a specific encoding. Also, technically speaking,
US-ASCII is a subset of UTF-8 and therefore you don't even need
an encoding declaration.

In your case, if the document is declared as "ASCII" and you can't
change that, just force Expat to treat it as "US-ASCII".
This is done by passing an encoding name to XML_ParserCreate.
