Problem parsing XML with encoding "US-ASCII" in AQXMLparser

[GerTeunis]

The parsing seems to keep starting over and over.
Perhaps the US-ASCII isn't detected/used correctly.
"US-ASCII is upwards-compatible with UTF-8 (an US-ASCII string is also a UTF-8 string, see [RFC 3629])"

When I manually change the encoding inside the xml to "utf-8" it seems to work okay.

I've added a rather temporary/dirty fix by added the following lines of code to AQXMLParser.m (line 371 in __startDocument)

if ([[[NSString stringWithCString:encoding encoding:NSUTF8StringEncoding] lowercaseString] isEqualToString:@"us-ascii"]) {
encoding = "utf-8";
}

I know; dirty but it works for the time being.
There doesn't seem to be a good stricmp or strcmpi available?
