I believe that it is near impossible for parsers to
support every character encoding, particularly given
that you can have your own encoding scheme (if both
parties understand it).
As you mentioned, UTF-8 has no limitations in
expressability and is universally understood. Taking
away the verbosity and processor requirements to parse
documents which contain mostly 16-32 bit data, you
have universal acceptance of your documents.
XML parsers are only one part of the picture. Apart
from the markup, the actual data also needs to be
processed by different applications. If you are using
composite libraries/applications, your best bet is to
deal with character encoding that is the most minimum
common denominator that is supported by those
libraries. And again, universal support for UTF-8
comes handy there.
