XQuery is one of those languages in which it's possible to write a
one-character quine (assuming you set the serialization options as
needed).
For example, using Saxon in a Unix-ish environment:
echo 1 > quine.xqy
java net.sf.saxon.Query quine.xqy \!method=text
produces the output "1".
(What other common languages similarly accept as input a single literal
value that is returned in output?)
