Hi, Pavils,
... Correct me if I am missing something:
AJAX frameworks presumably have no problem whatsover transferring data
directly in UTF-8 format. UTF-8 is the default encoding for XML. So, once
the data get to the client, all one has to do is parse the UTF-8 strings
directly out of the XML (assuming AJAX based on XMLHttpRequest) and wrap them
inside of some XHTML tags for display. Where is the need to escape strings
in XML? UTF-8 can encode all Unicode points.
