I have a XML document that references an external subset. Both are 
encoded in UTF-16. Xmllint seems to choke on the external subset file.
I haven't found anything about encoding problems with external subsets 
in the mail archives & bug list.

I'm working on a w2k machine.
I have attached the test used.

After some debugging I stranded in "xmlParserHandlePEReference" where a 
switch of encoding could be done; but the test fails, since "entity-> 
length" seems to be zero. I also have expected the "input" to be tested 
for length >= 4 and not the "entity" - but this one is zero as well. 
Since I don't know what length to use or how to fix this, I'm just able 
to point this out:

parser.c (xmlParserHandlePEReference)

                 * Get the 4 first bytes and decode the charset
                 * if enc != XML_CHAR_ENCODING_NONE
                 * plug some encoding conversion routines.
                if (entity->length >= 4) {   <<<----- HERE
                    start[0] = RAW;
                    start[1] = NXT(1);
                    start[2] = NXT(2);
                    start[3] = NXT(3);
                    enc = xmlDetectCharEncoding(start, 4);
                    if (enc != XML_CHAR_ENCODING_NONE) {
                        xmlSwitchEncoding(ctxt, enc);

Maby the line should read "if ((input->end - input->cur) >= 4)"?
Actually "input->length" seems not to be computed.

  looks like a bug, can you bugzilla this so this doesn't get lost ?

Done. Bug #135229.
