I am trying to write "Λ" on a sink.
(let ((sink (cxml:make-character-stream-sink *standard-output* :indentation 2 :canonical nil)))
(sax:start-document sink)
(xhtml-generator:write-doctype sink)
(xhtml-generator:with-html sink
(:html
(:head
(:title "Titel"))
(:body
((:p "style" "font-weight: bold")
"Inhalt")
(:ul
(:li "Eins")
(:li "Zwei") (:li "Λ")
(:li "Drei")))))
(sax:end-document sink))
<?xml version="1.0" encoding="UTF-8"?>
<html>
<head>
<title>
Titel</title>
</head>
<body>
<p style="font-weight: bold">
Inhalt</p>
<ul>
<li>
Eins</li>
<li>
Zwei</li>
<li>
&Lambda;</li>
<li>
Drei</li>
</ul>
</body>
</html>
