Expat does not natively support Big5. From the Expat reference manual:

    Parser Creation

    XML_Parser XMLCALL
    XML_ParserCreate(const XML_Char *encoding);

    Construct a new parser. If encoding is non-null, it specifies a
    character encoding to use for the document. This overrides the document
    encoding declaration. There are four built-in encodings:

     * US-ASCII
     * UTF-8
     * UTF-16
     * ISO-8859-1

    Any other value will invoke a call to the UnknownEncodingHandler.

Look under "XML_SetUnknownEncodingHandler" in the Expat reference manual
(member REF.HTML in source file EXPAT in LIBEXPAT) for information on how to
configure an unknown encoding handler.

I've never worked with Big5, but I did try to make one for EBCDIC and
failed. It seems to assume that certain characters will always match the
same values as they do in ASCII, even with an unknown encoding handler. If
your Big5 text is using an ASCII encoding, you'll probably be okay. If not,
you'll probably have to convert it to an ASCII version of Big5, and parse
that with your unknown encoding handler.

Also, it's not necessary to append x'00' to the string. (That was only
necessary in V3R2, starting with V3R7 we have options(*string)) just call it
as:
          p = XML_ParserCreate('Big5');
