Re: Character encodings

Hi,

we finally tracked down the character encoding issue to a problem in the 
Apache xmlrpc lib. I uploaded a patched xmlrpc library to

http://prdownloads.sourceforge.net/exist/xmlrpc-1.2-patched.jar

Replace the old jar in $EXIST_HOME/lib/core with the patched one and rename it 
to xmlrpc-1.2.jar (otherwise, start.jar doesn't find it).

For the interested, here's what I changed: 

in org.apache.xmlrpc.XmlRpc.parse() I replaced line 421:

parser.parse(new InputSource (is));

with

InputStreamReader reader = new InputStreamReader(is, getEncoding());
parser.parse(new InputSource (reader));

The SAX parser assumed a wrong encoding of the input stream - though the XML 
decl correctly declares UTF-8. I don't really know why. I tried different 
parsers, but the result has always been the same.

Also, org.apache.xmlrpc.XmlWriter.chardata() limits the range of valid XML 
characters to < 0xFF. I had to learn that the XMLRPC spec officially only 
allows ASCII characters to be used in strings. Everything else should be 
Base64 encoded. If we accept that, we can't use the string type anywhere. I 
have thus just removed the limit.

I'm not really happy with these fixes. I really think we should move from 
XMLRPC to REST as the main interface sooner or later.
