Re: Making a dissector for a text proto using ISO 10646 (Unicode) in UCS-2(was: Using external DTD)

About XML/DTD:

The XML dissector would need far more than FT_STRING_UNICODE to handle
XML with multibyte encoded chars .

The tvbparse API (on which the xml dissector) would need to be exteded
to handle multi-byte chars. And some parts of how to do it aren't
clear to me. What about multibyte chars in entities data and/or
entity/element/attribute names in DTDs?  That means that the DTD
parser needs to be extended as well.

\Lego

PS: In theory for adding support for an XML protocol all you need is
to write a DTD.
